As reports of a new strain of coronavirus in Maharashtra emerge, AIIMS Chief, Dr Randeep Guleria on Saturday, 20 February, told NDTV that herd immunity, especially in the case of the new Indian strains – found in Amravati and Akola – is a “myth” because at least 80 percent of the population needs to have developed anti-bodies to fight the virus.
The doctor added that the new strain is “highly transmissible and dangerous” and could cause re-infections for those who have previously developed anti-bodies. Guleria attributed the re-infections to “immune escape mechanism” of variants of the virus.
Advising people to maintain “Covid appropriate behaviour”, Guleria emphasised on the importance of getting the vaccine nevertheless, saying that although the person may not be immune to the new strain, they are likely to develop a milder version of it. Thereafter, the vaccine may be effective with reduced efficacy, added the report.
