COVID-19 Vaccines Benefits

Coronavirus [COVID – 19]

The Coronavirus pandemic also known as COVID-19, has caused negative effects across the globe; mortality and morbidity being the main impact. After WHO, termed the disease a pandemic in March 2020, they gave in health guidelines to follow to control the spread of the disease. The health industry, academia, and different governments are united to develop and test various vaccines at an unprecedented speed to combat the pandemic fully and bring the world back to its feet. Some of the vaccines developed include Pfizer, Moderna, and AstraZeneca.

However, just like other viruses, the SAR-CoV-2 virus keeps changing through mutation, as various variants, different from the first one is emerging. Evidence shows that the three new variants; UK, Brazil, Nigeria and South Africa are more severe in terms of transmissibility, disease severity, evading of the immune response, and reducing the ability to neutralized antibodies, compared to the original coronavirus. With such knowledge of the existence of different strains, this leads to checking on the benefits of COVID-19 vaccines, linked with the percentage of individuals benefiting from the already available vaccines are effective enough in preventing the new COVID-19 strains.

This research, through a systemic review of literature, seeks to find out benefits of COVID-19 vaccines whether the variants of SAR-CoV-2 have an impact on the efficacy of various vaccines developed in fighting the disease and the entire body’s immune response.

Introduction to Covid – 19 Vaccines

The world is struggling to rise again after being hit by one of the most tragic pandemics ever witnessed. COVID-19, a severe acute respiratory syndrome, has led to the collapse of the economy at the same time impacting the world’s health sector. With the virus comes a high rate of transmission, increased hospitalization, and death cases. Scientists, health departments, and various governments are working hand in hand to ensure that this disease is controlled (Lazarus, J., 2020). This seemed under control when various vaccines such as Moderna, Pfizer, AstraZeneca among many others, were developed to protect people from the disease (Mahase, et al, 2021). These vaccines showed a higher percentage of efficacy.

World Health Organization (WHO) on COVID-19 Vaccines

Equitable access to safe and effective vaccines is critical to ending the COVID-19 pandemic, so it is hugely encouraging to see so many vaccines proving and going into development. WHO is working tirelessly with partners to develop, manufacture and deploy safe and effective vaccines .

Safe and effective vaccines are a game-changing tool: but for the foreseeable future we must continue wearing masks, cleaning our hands, ensuring good ventilation indoors, physically distancing and avoiding crowds.

Concerns were reported about affordability and a lack of transparency on prioritization decisions and distribution of vaccines. Fears about forced and mandatory vaccination
were also circulating, creating fear, distrust and conspiratorial ideas.

Being vaccinated does not mean that we can throw caution to the wind and put ourselves and others at risk, particularly because research is still ongoing into how much vaccines protect not only against disease but also against infection and transmission.

See WHO’s landscape of COVID-19 vaccine candidates for the latest information on vaccines in clinical and pre-clinical development, generally updated twice a week. WHO’s COVID-19 dashboard, updated daily, also features the number of vaccine doses administered globally.

But it’s not vaccines that will stop the pandemic, it’s vaccination. We must ensure fair and equitable access to vaccines, and ensure every country receives them and can roll them out to protect their people, starting with the most vulnerable.

Scientist/Health Departments on COVID-19 Vaccines

With everything slowing down or coming to a halt, scientists and health practitioners have delved into trying to find a permanent solution so that life can go back to its normal. Multi-agency efforts on research have been facilitated in pursuit of developing vaccines for immunization to prevent COVID-19 infection. These vaccines have different working mechanisms to protect individuals against the disease.

The research on finding a vaccine and improved detection for the disease have moved at an unprecedented pace for reasons such as advancement in research, increased innovative vaccine technology equipment, the human trial was done at an early stage, and lastly great unity between relevant bodies 30. There are various vaccines developed to protect people from the transmission and adverse effects of the virus.

Preliminary data shows support for this statement as countries are reporting a decrease in the transmission rate. For instance, Africa claims to have vaccinated almost 75% of its older population, an action that has seen a 33% decrease in the transmission rate of the virus. Although, the impact of COVID-19 vaccines on the transmission of the disease has yet to be fully determined.

The Strategic Advisory Group of Experts (SAGE), through evidence-based medicine, gives temporary guidance on issues to do with immunization (Zhang Y., et al, 2021). Priority is given to health workers and people aged above 65 years because vaccines are limited and they also face a higher risk of getting infected.

COVID-19 vaccines Often Related to Safety and Side Effects

Survey participants reported concern about multiple issues: vaccine ingredients, rushed vaccine trials, and the use of mRNA-based technologies, among other concerns (Jeyanathan, 2020).

COVID-19 Vaccines and its Safety

There are many COVID-19 vaccines, both known and unknown, test run on individuals. Below are some of the lists of Covid-19 vaccines and its health benefits:

  1. Sinovac Vaccine, EV 71
  2. Moderna Vaccines
  3. Pfizer Vaccines
  4. mRNA Vaccines

Sinovac EV 71 vaccine

Sinovac vaccine (EV 71) was developed by a Beijing biopharmaceutical company. It works through killing viral particles that expose the immune system of the body to the virus. It uses dead virus particles to induce the production of antibodies;

AstraZeneca (AZD 1222) vaccine

It was developed and manufactured at University of oxford. The research name is AZD 1222 (ChAdOx1). The vaccine is administered through intramuscular injection with the commended dosage of two injections (0.5 ml each) given at an interval of 8 to 12 weeks between each injection (15-17). The body is then expected to be able to recognize and therefore develop a form of the protected response to the spike protein. This will help in stopping the entry of SARS-Cov-2 virus into the cells. The fact that AZD1222’ has a 63.09% efficacy for fighting against COVID-19 infection, creates the need to find long-term safety protection after one is given a single shot.

Moderna (Mrna-1273) vaccine

The vaccine, like its name, was developed by Moderna. The recommended dosage to be given to individuals above 18 years is scheduled into two doses (0.5 ml each) that are to be administered through intramuscular injections into the deltoid muscle. The interval between the two schedules is 28 days. The vaccine has shown the efficacy of 94.1% after a two months’ follow-up since it was first administered. According to WHO statistics, the potential benefits of this vaccine outlie potential risks (Wibawa T., 2021).

 mRNA-1273 vaccine was determined to have 94.1% efficacy for preventing symptomatic infection of SARS-Cov-2 in comparison to the placebo group.

The antibody lasts up to four months after immunization and it was approved the U.S. Food and Drugs Administration (FDA)

Pfizer vaccine (BNT162b2)

Pfizer has an active ingredient mod RNA that encodes the spike of SARS-Cov-2, the lipid hexane-6,1-diyl and salts such as potassium chloride, potassium phosphate and finally sucrose. Pfizer is 26% effective at preventing infection V on people who have not been infected before, which is then boosted to injection site (Cimerman S, 2020).

General COVID-19 Vaccines Safety

  • The vaccine reduces your risk of infection:

Once you receive your first shot, your body begins producing antibodies to the coronavirus. These antibodies help your immune system fight the virus if you happen to be exposed, so it reduces your chance of getting the disease. There are three vaccines available for use in the United States, and they are all more than 70% effective in preventing infection.

  • The vaccine helps your unborn baby or newborn.

A new study found that expectant mothers who receive the COVID-19 vaccine create antibodies to the virus and pass those to their unborn baby through the placenta. Mothers were also shown to pass antibodies to their newborns through breast milk. This suggests those newborns have some immunity to the virus, which is especially important as young children cannot get the vaccine.

  • The vaccine protects against severe illness.

During studies, the three authorized vaccines have shown to be effective at preventing severe illness from COVID-19. So even if you were vaccinated and become infected, you are very unlikely to become severely ill. The clinical trials for the Pfizer-BioNTech and Moderna vaccines showed they were 100% effective at preventing severe illness. The Johnson & Johnson vaccine showed 85% effectiveness against severe illness.

  • Protection against the new Strands of COVID

The vaccines are also effective against the new variants we’re beginning to see circulate, such as the Delta variant. Much like the original strand, all three vaccines will protect you against severe illness and reduce the likelihood for hospitalization.

  • The vaccine helped us ditch the mask

The vaccine is the final step in our effort to get back to a more normal way of life. Public health measures such as mask wearing, physical distancing and hand-washing were implemented to slow the spread of the virus, and they have proven to work. Although masks are still recommended indoors in areas with high infection rates, the vaccine is our path toward eventually moving beyond them.

Evidence suggests that vaccinated people who might be infected with the coronavirus have fewer virus particles in their nose and mouth and are less likely to spread it to others. This finding is important as getting vaccinated now not only protects you, but also limits spreading the virus to loved ones and friends.

As more people continue to receive the vaccine, we might reach herd immunity, which means the spread of the virus becomes unlikely. It’s important we all receive the vaccine to help us achieve this public health goal.

  • The vaccine will help you reconnect with friends and family.

Once you’ve received the vaccine and waited the recommended time for your body to build immunity, you can visit in person with other people who have been vaccinated without wearing a mask. Also, if you’ve been around someone who has tested positive for COVID-19, you do not need to quarantine if you are fully vaccinated and not experiencing symptoms.

After a year of uncertainty, the vaccine has arrived and has clear benefits that should make everyone strongly considered getting the shot. By choosing to be vaccinated, you can protect not only yourself and your family but your community as well.

Studies have shown vaccinated people who do get infected have mild to moderate cases of COVID-19 compared to those who aren’t vaccinated. So, your risk of hospitalization and death because of COVID-19 is nearly eliminated once you are fully vaccinated.

In Conclusion

The safety of COVID-19 Vaccines is of the essence to human existence. It’s true that you can still become infected after being vaccinated, but once more of the population is vaccinated, the chances of increased infection are further reduced immunity. So, getting vaccinated not only reduces your chance of being infected, it also contributes to community protection, reducing the likelihood of virus transmission which brings the COVID-19 safety to a positive side in our daily lives.
