Countries are advancing at a sustained pace with their vaccination campaigns and Coronavirus cases are slowly falling in the world after the impact of the Omicron variant in December and January. In Argentina, 98.4 million vaccines have been applied and 37 million people have the complete schedule (two doses) while 20.5 million have already received the additional or booster dose.
Globally, according to data from OurWorldInData, 65% of the world population has received at least one dose of the serum against the Coronavirus, and 11.47 billion doses have been administered.
One of the most widely used vaccines is that of Pfizer-BioNTech, applied in 158 countries, behind that of Oxford-AstraZeneca, which is used in 183 nations, according to figures from the Statista site.
Pfizer Announces How Often You Will Need to get the Covid Vaccine
It is possible that a situation between endemic and epidemic occurs, where Ómicron evolves. Therefore, an annual booster dose will be needed.In this context, a recent report from the pharmaceutical company reveals that it will have to continue vaccinating against Covid in the following campaigns. According to the investigation, one more dose per year will be necessary to be protected.
Luis Jodar, global medical director of Pfizer explained the reasons why it is necessary to continue with the vaccination: “It is possible that a situation between endemic and epidemic will occur, where Ómicron will evolve. Therefore, it is very likely that all older people groups need booster doses every so often, for example, a year.
Jodar has also pointed out what the solution to this annual vaccination could be: “It would be doses adapted to each variant, until a universal vaccine is found that is impervious to each mutation.”
