Even as more cases of breakthrough COVID-19 infection are reported, especially among the medical fraternity, there has been no talk about a booster dose for healthcare and frontline workers. There are over 1.47 lakh healthcare and frontline workers who received their second dose of the COVID vaccine six months ago. Last week, 29 students at KEM Hospital tested positive for COVID-19. 

The BMC started the vaccination drive for frontline and healthcare workers in January and the second dose vaccination started on February 15, in keeping with the advised gap between two doses at the time. By the end of March, 82,852 healthcare workers and 64,304 frontline workers got the second dose, along with 314 senior citizens and 56 citizens in the 45 to 59 age group. With six months having passed since the second dose, there are questions over decreasing antibodies with time.
