Washington: US Chief Medical Adviser Anthony Fauci said that it is “conceivable” that a fourth dose of Covid-19 vaccine will be recommended to protect against Omicron variant.
Fauci has said, “it’s “conceivable” that a 4th dose of Covid-19 vaccine will be recommended to protect against Omicron variant. So we’re going to take one step at a time, get the data from the third boost and then make decisions based on scientific data.
Meanwhile, just last month a study released by Israel’s health ministry found that fourth vaccine dose for older adults leaves them better protected against coronavirus infection than peers who received three shots.
The preliminary analysis compares data from about 400,000 people aged 60 and over who received a fourth dose in January and some 600,000 people in the same age group who got only three doses — with the third shot administered four months or more previously.
The researchers found that those who had the fourth dose had twice the protection from infection as the others, and at least three times the protection from severe illness.
