Experts also say that antibodies do not tell the whole story. Our immune system has an additional line of defense, called B and T cells, to fight intruders like viruses.
How long does protection from covid-19 vaccines last: Vaccination has also started amidst the havoc of corona virus worldwide. Amid the second fierce wave of Corona in India, the Central Government has approved the introduction of vaccine to all people above 18 years of age. But questions are arising in the minds of people that how long can the vaccine protect us from COVID-19? Will we never get infected with this deadly virus after getting the Corona vaccine? Experts have tried to answer these questions.
Experts say that the exact answer to this question has not been found because studies are still going on. It is being seen that how effective the vaccine proves to be in fighting the new variant of Corona and how much time the vaccine will have to be added. University of Washington researcher Deborah Fuller says, “Only after doing a deep study on the vaccine will one get to know about it.” We have to study those people who have been vaccinated. It will have to be seen at what stage these people again increase the risk.
Pfizer’s vaccine works for so many months
Researcher Deborah Fueler said that from the indications so far obtained from the trial, it can be said that two doses of Pfizer Vaccine are effective in fighting this deadly virus for at least six months. Those who have got antibodies in Moderna’s vaccine too for so long to fight the virus. This means that the vaccine can also fight the virus for about 6 months.
Antibodies do not tell the whole story
Experts also say that antibodies do not tell the whole story. Our immune system has an additional line of defense, called B and T cells, to fight intruders like viruses. Many of these remain for a long time, even when the antibodies start running out. When these cells encounter the same virus again, they start working faster to fight it. Even if they do not prevent you from getting sick, they do not allow the situation to become serious.
No lifetime guarantee
University of Maryland vaccine specialist Dr. Kathleen Newsill says that the effect of the vaccine may last for one year, but it does not guarantee that it will make you safe for life. He said that the effect of this vaccine can last between six months to one year. However, additional doses may be required due to the variant.
Vaccine may have to be taken as the virus is mutant
Mehul Suthar of the Emori Vaccine Center says that the corona vaccine has been developed in such a way that a particular type of protein fights against the coronavirus. If the virus mutates in the future, the vaccine may need to be taken again. Corona vaccine is effective against all the variants that have come so far. However, the vaccine is proving to be slightly less effective against the variants found in South Africa.
