Health/Covid-19: New vaccines in perspective
The American Giant Pfizer and his German partner BioNTech announced last week the launch of a new phase of the clinical study on a modified vaccine against Covid-19, with the objective of achieving stronger, more durable and broader post-vaccination immune responses.
This information comes just over a month after the company announced Moderna an update of its vaccine against the BA.4 and BA.5 subvariants of the Omicron strain of Covid-19.
In the meantime, experts warn that people at high risk of serious illness who have not yet received a second Covid-19 booster should not wait for the next generation of vaccines, scheduled for the fall. ” If you need a reminder, do it now said Dr. John Moore, professor of microbiology and immunology at Weill Cornell Medical College, At New York. Doctors believe that the best booster for those at risk is one that is close at hand. Dr. Bob Wachter, chief of the department of medicine at the University of California, San Francisco, said the evidence is becoming clearer: the further a person is from their last recall, the less it is protected against infections and serious illnesses.
In Egypt, the Ministry of Health has recommended a booster dose every three months for citizens over 65 and for chronic or autoimmune patients, and every six months for the rest of the population. To date, 6 million Egyptians have received a booster dose.
