Should You Get The COVID-19 Vaccine Every Year? Here’s What Experts Say!

SARs COV-2 or coronavirus wreaked havoc worldwide. Thousands of people lost their loved ones and the increase in the rate of infection led to such a state that the whole world had to go through a complete lockdown. 

While scientists and medicinal professionals actively searched for ways that could help in eradicating the virus, the virus mutating its form constantly, became a primary source of concern. 

After a year of persistence, vaccines were finally developed against coronavirus that helped in bringing down the cases of the infection. 

However, according to medical experts, these vaccines may not be able to protect against the SARS COV-2 virus lifelong and there might be a need to get the COVID-19 vaccine every year.

1. How do COVID-19 vaccines work? 

Before we move on to state why we need the COVID-19 vaccine every year, let us first understand how the COVID-19 vaccination works. 

The vaccine works by introducing our immune system to an inactivated form of SARS-CoV-2 coronavirus. This causes our body to be equipped for any future cases of infection. The vaccine helps in producing memory T-lymphocytes and B-lymphocytes that help in remembering how to fight the virus in the future. 

The most popular type of vaccines that are used against the COVID-19 virus is mRNA vaccines, protein subunit vaccines, and vector vaccines.

2. Why do we need to get the COVID-19 vaccine every year? 

Medical experts have suggested that the acquired immunity obtained from the COVID-19 vaccine may slow the spread of COVID by decreasing the cases of infection, however, the immunity acquired may diminish over time. 

It has been observed that fully vaccinated people have succumbed to the clutches of the deadly virus and that has led to the solidification of the hypothesis of waning immunity. 

Like as mentioned above, vaccination helps in triggering our immunity at different levels- an early B-cell mediated antibody response and a delayed T-cell mediated response. 

Therefore, the sustainability of the vaccines depends on a variety of factors including the individual’s response to the vaccine and efficiency and effectiveness of the T-cells, and that the antibody may wane over time and cause a rise in the cases again. 

And in order to prevent a global pandemic again, countries like Israel and the United States of America are developing booster vaccines that will help in preventing the waning of the acquired immunity. 

3. What will be the role of these yearly booster vaccines? 

The SARS-CoV-2 coronavirus has mutated several times over the last year and each time it has emerged more powerful, making it more uncertain for scientists and medical experts to decipher its characteristics. And therefore, the demand for booster vaccine shots or yearly vaccines has increased. 

Medical experts have suggested that the booster shots will be administered to a person to re-expose the immune system to the antigen and boost the capability of the body to produce new antibodies against the mutated forms. 

The vaccines provided now generally will be protected for 8 months to 1 year, before one again is at the risk of succumbing to the deadly virus.

Booster shots, therefore, are required until people develop herd immunity and yearly vaccines will no longer be required. 

Now one may wonder, that the yearly booster shots may be different from the regular vaccines but according to medical experts, the only difference between the vaccine shots will be the purpose that they will serve. 

The initial COVID-19 vaccinations are generally administered to produce enough COVID-19 antibodies to fight off the virus. But, the booster shots will be administered at a time when the effects of the first rounds of vaccination are expected to decline. 

Precautions to follow while receiving COVID-19 vaccine

There are certain precautions that one should follow while getting the COVID vaccine

  • Do proper research before you receive the vaccine from a particular center. 
  • Check whether you have an allergic reaction to any of the ingredients of the COVID vaccines. 
  • Make sure you are not ill when you receive the vaccine as chances are high that the vaccine can potentially deteriorate your condition. People experiencing symptoms of COVID-19 are advised to be completely recovered or approved by the doctor before receiving the vaccine. 
  • Before receiving the vaccine, one should be well hydrated and receive a good night’s sleep. 
  • After receiving the vaccination, monitor your health and prepare yourself for the potential side effects. The probable side effects that are generally observed after getting vaccinated are arm soreness, mild fever, headaches, or muscle and joint aches.

Now there you go, everything you need to know is whether we will get the COVID-19 vaccine every year or not. 

The SARS-CoV-2 coronavirus claimed thousands of lives the previous year causing a global pandemic and is continuing to do so with its frequent mutations. 

However, with the development of the COVID-19 vaccination, cases of infection have gradually decreased. But according to medical experts, the acquired immunity provided through the vaccines is short-lived and will start to wane over time, and that there is a dire need to provide booster vaccine shots to withhold immunity against the deadly virus. 

Therefore, to summarize, there needs to be several more studies and researches that will solidify the claims of booster vaccine shots. 

And as mentioned above, there have been several instances where people despite being vaccinated have succumbed to the deadly clutches of the coronavirus. 

Hence, till the development and trial of booster shots, observe the following points to protect yourself and those around you from the virus

  1. Follow social distancing. Avoid going out if you do not have to. 
  2. Wearing a mask is an absolute must if you are in public or in a place where social distancing is not possible
  3. Follow proper hygiene practices. Keep yourself and your surroundings clean. 
  4. Use hand sanitizers and while coming back, sanitize your clothes and belongings before you bring them inside your house. 

Also, consult your medical provider immediately if you observe symptoms of COVID-19, for proper guidance, medication, and treatments.
