Why Some People are Hesitant to Take Covid-19 Vaccines. With reports that three Congress Members in the United States, who have been vaccinated with doses of covid-19 vaccines have tested positive for the virus; doubts now seem to trail the much awaited vaccines which were hitherto welcomed with enthusiasm. However, experts say cases like these are not surprising and do not indicate that there was something wrong with the vaccines or how they were administered. They say vaccines don’t work instantly. It takes a few weeks for the body to build up immunity after receiving a dose. And the vaccines now on use in the united states, from Pfizer BionTeach and Moderna, both required a second shot a few weeks after the first to reach full effectiveness. They also explained that the vaccines does not work retroactively, noting, “you can already be affected and not know it, even if you recently tested negative, as the infection can continue to develop after you get the shot but before its protection fully takes hold, and then shows up in a positive test result”. Experts emphasize that the vaccines prevent illness, but maybe not infection. They note that Covid-19 vaccines are being authorized based on how well they keep you from getting sick, needing hospitalization and dying. Scientists don’t know yet how effective the vaccines are at preventing the corona virus from infecting you and from passing it on to others; maintaining that it is why vaccinated people should keep wearing masks and maintain social distancing. They said even the best vaccines are not perfect. The efficacy rates for Pfizer-Bion Ntech and Moderna vaccines are extremely high, but they are not 100 percent. According to DH Herald,vaccines are proven to reduce deaths and help end pandemic. However currently available vaccines are highly effective against symptomatic illness. It takes about two weeks after the second dose to offer that high degree of protection, according to infections disease experts. However, the historic speed by which the corona virus vaccines have been developed, has made some people hesitant to take them.
