Most vaccines developed against the coronavirus require two doses. This is the case of Pfizer, Moderna, AstraZeneca or Russia’s Sputnik. In contrast, only Johnson & Johnson’s is administered in a single puncture. But in the case of the above, not completing the guideline has its risks.

As stated in a report the BBC, not taking the second dose means that the person is not properly protected. “The data we have shows that the person is protected with two doses. If he takes only one, he has not completed the plan and is not properly vaccinated“, says Dr. Isabella Ballalai, vice president of the Brazilian Society of Immunizations.

It is true that the first dose already gives protection, but not within the parameters established by institutions such as the World Health Organization (WHO).

Another downside to sticking to just one dose is the false sense of security that the vaccinated person may have, lead a normal life and think that they are immune to Covid-19.

And what happens if a person who has received the first dose does not receive the second? ¿Must start from scratch or can the second dose be given at any time?

“If the maximum time to receive the second dose has been exceeded, it may be necessary restart the vaccination schedule, since all the efficacy data that we have are based on a protocol “, points out the immunologist Cristina Bonorino, professor at the Federal University of Health Sciences of Porto Alegre.” If we do not stick to this, we cannot guarantee the immunization, “he adds.

“They should not be delayed, but if they have something unforeseen, it is important to receive the second dose as soon as possible to get a good immune response, “says Isabela Ballalai.

“We need this information to be disseminated on television, on social networks and in all the media, so that the populationn don’t forget to take the second dose of the vaccine in the indicated dates “, concludes.
