How long does the Covid vaccine last?

In 2020, the name Covid-19 will surely be remembered by almost everyone in this world. This is the name of a deadly virus that caused a global pandemic in early 2020 and is still going on until now. Starting in December 2019, this virus was firstly discovered in Wuhan state, China. Since then, it has affected many people and most of the countries in this world have suffered from its infectivity. Because Covid-19 virus can spread and infect other people very quickly, the WHO (World Health Organization) had to declare this virus as a pandemic in February 2020. At that time, millions of people in a lot of countries were affected and thousands had died from this infection. This situation calls for a solution in order to solve this problem and save humanity. As for now, the one and only solution is to develop a Covid 19 vaccine that aims to neutralize this infection as quickly as possible.

In mid-2020, it was announced that some manufacturers had started to work on vaccine production. By early 2021, the vaccines are ready to be used and tested in our population. There are three notable vaccines as of March 2021. These include Pfizer, Moderna and Johnson & Johnson vaccines. A lot of countries have started to give vaccine injections to their people. You might be one of the vaccine receivers that will soon receive your shot. While the process is a long one due to the high number of applicants, it is the best recommendable action that you can do right now. This is because the vaccines that were stated above were proved to be very effective in helping to fight Covid-19 and reduce its infectivity. Statistics have shown that Pfizer, Moderna and Johnson & Johnson vaccines have 95%, 94.1% and 85% effectiveness respectively.

While you are waiting for your turn, you might be wondering about how long will this Covid-19 vaccine work? How long does it last and does it expire? To answer this question, we need to look at our reality. These vaccines are very new and most of them were tested in early 2021 to be exact. Hence, researchers still do not know how long it will last in human’s bodies because the process is still under supervision. As for now, it is quite effective and researchers need to supervise these vaccine’s effects for a long time before they can come to a conclusion about the vaccine’s longevity. However, based on the research that was done before the vaccine was distributed, scientists think that Covid-19 vaccine can last for at least 3 months. Some researchers come out with a different view and claim that these vaccines can last around 4 to 6 months.

However, this claim is still a hypothesis. As mentioned above, researchers need more supervision time before they can give their conclusion on how long the vaccine will last. They also mentioned that some factors can help change the longevity of a Covid-19 vaccine. The main factor will be the individual’s immunity. Someone with a higher immunity level will be able to help the vaccine’s effect last longer in their body. Besides, another factor will be the virus mutation. For now, the vaccines are designed to fight all the discovered strains of Covid-19. But, if a newly formed mutation happens, the vaccine has a possibility to be useless against that strain. So, the most important thing to do right now is to distribute the vaccine to all the people as quickly as possible. Our real enemy is not a virus, but we are fighting against time right now.
