Runny nose, headache, sneezing, sore throat and persistent cough. These are the five most common symptoms in people who have been vaccinated after taking two or more doses of the vaccine.
People who have not been vaccinated have the most common symptoms of the disease, in descending order, headaches, sore throats, runny nose, fever and persistent cough.
The results came from a follow-up in the UK two years ago using an app developed by technology company Zoo.
The data was analyzed in partnership with researchers at King’s College, a London-based university, in collaboration with the country’s public health system, the NHS.
More than 4.7 million users registered on the online platform only need to report these symptoms when they feel positive when testing positive for Quaid.
From there, experts analyze all this information and compile a classification of common symptoms, which have changed significantly over the weeks and months of epidemics.
The work, which received funding from the UK government as of March 2022, was instrumental in quickly identifying some of Wood’s least anticipated problems, such as sniffing and lack of taste.
See below for the most common symptoms of the disease, depending on the dose of the vaccine given.
Minor but relevant change
The most common symptoms of codeine in people who have received at least two doses of the vaccine are:
- Runny nose
- Sore throat
- Persistent cough
Among those who did not take any food, there are some changes in the top 5:
- Sore throat
- Runny nose
- Persistent cough
The main difference is the presence of fever in people who have not been vaccinated, which indicates a more serious condition. They also report more headaches and sore throats than people who took two or more doses of immunosuppressants.
“We also need to consider that a large number of cases are reported in young people, with different and less severe symptoms.”
The authors believe that the classification of symbols is based solely on the information shared in the application. Therefore, it does not take into account the circulation of certain types of corona virus.
And it is worth noting that the symptoms of cod can be very different. According to the UK Public Health Service, the full list of common manifestations of the disease includes:
- Persistent cough
- Odor reduction or change
- Decreased or altered taste
- Difficulty breathing
- Fatigue or tiredness
- Body aches
- Sore throat
- Stuffy nose or runny nose
- Loss of appetite
- Feeling sick, nauseous and nauseous
According to national and international authorities, if you show one or more of the common symptoms of corona virus infection, the first step is to stay home and limit communication with others.
This is even more important if you come in contact with people who suffer from colic complications, such as the elderly or patients with weakened immune systems.
In this context, another important step is to get tested to confirm or rule out the disease.
In addition to RT-PCR, which is considered an important and reliable diagnostic method, it is possible to find rapid antigen tests in pharmacies and laboratories across the country.
If the result is really positive, it is necessary to stay in solitude for five to seven days.
If the discomfort improves after this time, it is possible to resume normal. Now, if they get worse (or other serious cases appear, such as shortness of breath), it is important to find an emergency room.
This information is particularly relevant now, at a time when there is a new increase in cases of cod in Brazil: according to the National Council of Health Secretaries (CONS), the average daily movement of new infections is 39,800. The rate was 13,700 on May 20, a month ago.
Paying attention to the symptoms – and how they may vary depending on the amount of vaccine administered – is also important in the Brazilian context. So far, 78% of the country’s population has received two initial doses and 48% have received a booster.
Why do vaccinated people get cod?
Vaccines currently available against covid are developed with one primary goal in mind: to reduce the risk of the most serious complications of the disease, including hospitalization, intubation and death.
Regardless of the type of technology used, the vaccine has one primary purpose: to safely protect our immune system from any viruses or bacteria (or specific fragments of it).
From this first contact, which will not harm health, our defense cells produce a response, which is able to leave the body ready if it decides to reveal a real infectious agent.
It turns out that this immune process is extremely complex and involves a large battalion of cells and antibodies. Therefore, the immune response can vary considerably, depending on the type of virus, its ability to mutate, the way the vaccine is developed, and the state of human health.
In the midst of all these processes, therefore, it is very difficult to develop an immune agent that is capable of preventing infection itself, that is, preventing the entry of the cause of disease into our cells.
But here’s a very important point: even in cases where the vaccine can’t stop the infection, the immune response that often arises can make the symptoms less severe in people who have been vaccinated, thus more severe. Diseases and deaths can be prevented.
This happens, for example, with vaccines against rotavirus and the flu: anyone who takes them can become infected, but the risk of developing more serious forms of these diseases is significantly lower. Gets done
And that’s exactly what we’re seeing now with CoVID-19: even if the available immunizations aren’t able to stem the new wave of cases, they do a great job of preventing the worsening of most infections. Are working
Evidence of this is the recent surge between the end of 2021 and the beginning of 2022, which has to do with the spread of the omikron type: although many countries have broken absolute records of cases, hospital admissions in these places And the mortality rate is significantly lower than in previous epidemics.
A study by the US Centers for Disease Control and Prevention (CDC), published in March, calculated the size of the protection. Statistics show that adults who have received three doses of the vaccine against cod have a higher risk of hospitalization, mechanical ventilation or death than those who have not been vaccinated. The risk is 94% lower.
One-third of the evidence of this protective effect comes from Zoo and King’s College’s own follow-up, mentioned at the beginning of this article.
Severe symptoms of cod, such as difficulty breathing and high fever, were more common at the onset of the epidemic, when vaccines were not yet available.
With wave of cases and mainly food consumption in a large part of the population, this expression dropped in the rankings, and gradually turned into relatively mild ailments, such as runny nose, headaches at the top of the reports. And sneeze.
From a practical point of view, in people who have been vaccinated with two or more doses, the corona virus can also attack cells in the mouth, nose and throat, where it will cause specific symptoms of the common cold.
Fortunately, in most of these cases, the immune system soon becomes active and prevents the pathogen from reaching the lungs and the rest of the body, where it causes shortness of breath, fever, inflammation and other serious consequences.
Currently, the Ministry of Health recommends a fourth dose of the vaccine against covidone for people over 40 years of age or for those with immune problems.
Three doses are recommended for people aged 13 to 49. For children 5 to 11 years old, the first two doses are in progress.
