Living with Covid-19 for almost a year and two months, we have already learned a lot about the transmission of the virus and, currently, the importance of vaccination for us to return to a relatively normal life in the medium term. But, as disinformation unfortunately runs rampant on the internet and social networks, there are many fake news that are transmitted as real news.
To help anyone who has doubts about aspects such as vaccine efficacy and possible dangers that they could bring to the human body, we have collected below some of the most common false news related to this topic. Check out:
Myth 1: the young population does not need to be vaccinated
There are several cases of people in their 20s and 30s who became seriously ill because of the disease. It is important to remember that even those who have not had breathing problems due to the virus can have some of the symptoms even months after contracting the disease, ranging from loss of smell and taste to fatigue and cognitive problems.
In addition, deaths of young people aged between 20 and 29 by Covid-19 grew almost four times in the state of São Paulo between February and March 2021.
Myth 2: we are unaware of the long-term effects of vaccines and this can pose a risk to people
We do not know whether Covid-19 vaccines will trigger an immune reaction in the coming months or years, but the likelihood of this happening is extremely low, according to experts in the field.
“Historically speaking, adverse reactions caused by vaccines almost always appear in the first two months,” he explained in an interview with Mashable Dr. Thomas Russo, head of the Department of Infectious Diseases at the University of Buffalo.
Myth 3: if even those who are vaccinated can still catch the virus, it makes no sense to get vaccinated
It is important to say that no vaccine has 100% protection. This is because the viruses that originate the disease undergo mutations that end up “negating” previous vaccines, as in the case of influenza.
The main role of vaccines is to prevent or alleviate the symptoms of the disease. Using Coronavac as an example, a study released in April by the Butantan Institute found that the vaccine has an overall effectiveness of 62.3%.
Myth 4: a person who is vaccinated and who, therefore, has Covid-19’s “viral load” inside him, can pass the virus to those who have not yet been vaccinated by physical contact
This theory emerged from a fake news spread in the USA and known as “vaccine shedding”, in which vaccinated people could infect others since they would have a live form of the virus inside them.
“The tiny proteins produced by the vaccine to trigger an immune response to the virus cannot” spread “out of the body, remain miraculously intact and stable, and then negatively affect other people. It is biologically impossible “, said doctor Thomas Russo to the Mashable.
Myth 5: my immune system will know how to cure me of the virus
Let’s agree that letting your immune system fight a disease that can damage your respiratory system doesn’t seem like a very wise solution. Vaccination is the best way both to prevent serious diseases and not to overburden the health system.
Another negative aspect of “letting the body overcome the disease” is that this tactic can cause variations of the disease that are resistant to the vaccines already created. An example is the variation that emerged in Manaus: although the vaccines are effective against it, the effects of this version of the virus are usually stronger than the strain that arrived in Brazil last year.
