The World Health Organization (WHO) has recommended today that people who are vaccinated against covid-19 receive doses from the same manufacturer, And therefore if they receive first one of the developed by Pfizer-BioNTech the second is also from this pharmaceutical.
“There could be some practical considerations, in some countries where there is no other option it would be better to vaccinate with two different products than not to do so, but in principle we do not recommend it,” said the WHO director of immunization. , Kate O’Brian, in a meeting through social media.
At the same forum, Mexican Alejandro Cravioto, chairman of the Strategic Advisory Group of Experts studying new vaccines by the WHO, added that it is recommended not to receive vaccines against other diseases until two weeks after receiving the intended one to protect against the coronavirus SARS-CoV-2.
Cravioto also stated that there is evidence that the possible side effects of these vaccines in the older population are less common than in the younger ones.
“We have no reason to think that the vaccine could be harmful to those over 65,” Cravioto said.
According to these experts, the most observed side effect has been some allergic reactions, So it is requested that the centers administering the vaccine be able to treat these anaphylactic shocks immediately.
Another effect observed in very small numbers of patients in whom clinical trials were performed were cases of non-lasting facial paralysis, fever, or general malaise, which are not considered reasons why the vaccine should not be received.
