Since December 27, 2020, when she became the first Spaniard to be vaccinated against Covid-19, more than 95 million doses have been administered in our country.
In total, 92.7% of the population over 12 years of age has the complete regimen (40,550,392 people).
And although it has been repeated over and over again, people vaccinated against him they can be infected.
This, however, does not mean that immunization is not effective, but rather that it prevents the development of the disease. serious illnesswhich could lead to hospitalization and, in the worst case, death.
However, a study by the University of London, in collaboration with the , has revealed that the symptoms between inoculated people and those who are not are very different. And the number of doses also influences.
Thanks to the ZOE COVID Study application for mobile devices, it has been possible to identify the five main symptoms of SARS-CoV-2 and how they differ depending on whether one is vaccinated or how many doses have been received.
In Spain, the booster dose (the third) is administered to all people over 12 years of age who have previously been vaccinated with the full schedule. The fourth dose, which at one point was going to be for the entire population, will initially be for those over 80 years of age and residential users.
What are the symptoms if I have the full regimen?
The authors of the study explain that “the symptoms they are similar in people who had been vaccinated and those who had not.
However, those who had already received a dose report fewer symptoms for a shorter period of time, suggesting that they get less severely ill and get better faster.”
-
Runny nose.
-
Headache (headache).
-
sneezing.
-
Sore throat.
-
persistent cough
The symptoms that in the first waves of the coronavirus were more characteristic of the infection, such as anosmia (loss of smell), shortness of breath or fever, are now less frequent. And the cough, the researchers emphasize, “is no longer the main indicator of having COVID.”
In addition, people vaccinated with the full course and infected with SARS-CoV-2 are more likely to suffer sneezing against those who have not been vaccinated.
Therefore, “if you have been vaccinated and start sneezing without explanation, you should get a COVID test, especially if you live or work with people who are at higher risk of contracting the disease,” they emphasize.
What are the symptoms if I have only received one dose?
The main symptom is a headache along with a runny nose. It is followed by a sore throat, sneezing and a persistent cough.
What if I am not vaccinated?
People who have not received a single dose against the coronavirus tend to suffer from a greater headache, sore throat, runny nose and fever.

“Loss of smell is number 9 (in the ranking made by users on the APP) and shortness of breath is well below the list, at number 30. This indicates that the symptoms are changing with the variants of the virus”.
What is the epidemiological situation in Spain?
According to the latest data provided by the Ministry of Health, 52,218 new cases of coronavirus have been reported. In the last seven days there have been 152 deaths, bringing the total number of deaths since the start of the pandemic to 107,906.
So, the incidence of infections in the last 14 days in people over 60 years of age is 841.27 cases per 100,000 inhabitants.
In recent weeks there has been an increase in infections due, in large part, to the new omicron sublineages, BA.4 and BA.5, which are gaining ground in our country.
According to a study by , and published in the New England Journal of Medicineomicron variants “escape” immunity acquired by previous infection or vaccination.
Therefore, they are “more contagious”, but they do not cause SARS-CoV-2 disease to be more severe.
