In recent weeks, the cumulative incidence of the coronavirus has not stopped increasing. Covid-19 is infecting even people who have already received a dose of the vaccine. In this situation, a question arises: What happens to my second dose if I caught it after receiving the first?
According to latest update of the vaccination strategy, people under 65 years of age who have been infected after receiving the first dose will be given a second dose after six months from the onset of symptoms or diagnosis.
In this same case but in people over 65 years, the second dose will be inoculated when they are fully recovered and the isolation period is over.
Another situation included in the vaccination strategy is contagion before receiving the first dose. In this case, those under 65 only one dose will be administered preferably from six months after the onset of symptoms or diagnosis of infection.
For their part, the people over 65 years that have been infected before the first vaccination schedule, they will be administered the two doses when they are fully recovered and the isolation period is over. In this case, do not wait six months after infection for the inoculation of the first dose.
The perception of Primary Care
In primary care consultations, the perception is that more people are attending who have been infected after receiving the first dose of the vaccine. “We are seeing relatives of adolescents who are still waiting for the second dose,” he says. Lorenzo Armenteros, Covid spokesperson for the Spanish Society of General and Family Physicians.
Symptomatic disease is seen in these people, “mild but symptomatic“He also claims to have seen symptomatic people with both doses of the vaccine,” although they are almost always asymptomatic. We cannot know if that patient, if not vaccinated, would have developed the disease “in a more serious form.
Armenteros warns of the contagiousness of the Delta variant. “They are contagions that occur in some cases only with a contact of minutes without a mask.” Its effects are not only being seen in Primary: the increase in hospital admissions is already a clear trend and in just two weeks the number of beds occupied by Covid patients is about to double.
Among those hospitalized there are also people who had received the first dose of the vaccine and were waiting for a second. “There are not many, anyway,” he points out. Jose Manuel Ramos, an internist at the General Hospital of Alicante and coordinator of the infectious diseases working group of the Spanish Society of Internal Medicine.
However, “they may not be as bad as the rest of those admitted by Covid,” he indicates. “We came to have the case of a patient, very old, who had received both doses, and was very bad. But she had a basic disease, heart failure, aggravated by Covid.”
The fact of having passed the disease having received one dose may make some of the patients think that their immunity will have developed in such a way that a second is not necessary, but Lorenzo Armenteros explains: “For there to be a multiplicative effect of the antibodies, there must be time between the first and the second dose., or between the disease and the dose of the vaccine, because the vaccine multiplies those that already exist, that is why a booster is needed. “
For this same reason, those who have passed the Covid only need to receive a single dose of vaccine, since it is the booster that will multiply the humoral immunity already obtained naturally. Although countries have established different periods of time to inoculate that second dose, the important thing is that there is a certain distance.
