Immunity begins to decline in 6 to 8 months
Fortis C-Dock President Dr. Anoop Mishra said that there is no shortage of vaccines in India, so why delay in vaccination? “We know that the immunity developed by the vaccine against the corona virus decreases after six to eight months,” he said.

Fourth dose is allowed in Israel, US, UK
Countries such as Israel, the United States and the United Kingdom have already given three vaccines against Covid-19 to their citizens. An additional fourth dose of the vaccine has been approved in these countries due to the increase in cases of corona. In January, the government approved an additional dose of the vaccine for health care workers and the seriously ill elderly. Recently, it was clarified that anyone over the age of 60 can take a third or booster dose.
People with serious illnesses should be allowed
Renowned immunologist and former dean of AIIMS, Dr NK Mehra, told TOI that the country now needs to allow booster doses as the first two doses of the vaccine weaken the immune system in six to eight months. Dr. Mehra said that for example, annual shots are recommended for people who are resistant to the common flu virus and the elderly. He said that apart from the elderly, the government should allow booster doses for anyone in India who is suffering from a serious illness.
