what risks increase after receiving the vaccine

As studied, vaccines reduce chances of getting coronavirus. In addition to further protecting hospitalization and death. However, it is important to account for infections in vaccines as the protection of the vaccine may decrease over time.

For this reason, some governments are considering offering a booster dose to the most vulnerable. Among them is France and Germany who are already planning to offer additional doses to groups they consider to be at higher risk.

What are the symptoms of “vaccinated infection”

Headache, runny nose, sneezing, sore throat and loss of smell, are the five most common conditions of an infection in vaccinees, according to the Study of the symptoms of coivd-19.

On the other hand, headaches, sore throats and runny nose are the same symptoms how infected people may feel who have not been vaccinated.

The other two most common symptoms in unvaccinated people are fever and persistent cough. They both turn most atypical once the vaccine has been received.

One study concluded that people infected with vaccines have a 58% less likely to have a fever than unvaccinated people. To many, Covid-19 looks like a cold after vaccination.

These people also less likely to be hospitalized if they develop the disease. They are also likely to have fewer symptoms during the early stages of the infection and are less likely to have the disease in the long term.

The reasons why the disease is milder in people who are vaccinated could be because the vaccines, while not completely blocking the infection, can cause the infected person to have fewer virus particles in their body. Although this is not fully confirmed.

Four factors that increase your risk after being vaccinated

In the United Kingdom, the investigation concluded that the 0.2% of the population, or one in 500 people, you get an infection after you are fully vaccinated. Not everyone runs the same risk since there are four factors that can influence the protection of a citizen after being vaccinated:

1-Type of vaccine

It is because of specific type of vaccine that someone is already receiving the relative risk reduction It offers.

So far, clinical trials have shown that the vaccine Moderna reduced symptomatic risk by 94%, while the vaccine 95% Pfizer.

Vaccines Johnson & Johnson and AstraZeneca have lower percentages, reducing this risk by about one 66% and 70%, respectively.

2-Time elapsed since vaccination

The time since vaccination is also important. And that’s one of the reasons the debate over an extra booster is gaining momentum around the world.

Early research suggests Pfizer vaccine protection is waning for six months after vaccination. Although there is still much to be studied regarding the different vaccines, it is likely that – after the six months have elapsed – inoculation efficiency is further reduced.

3-Variants

The risk reductions mentioned above were largely calculated by testing vaccines against the first type of virus. SARS-CoV-2.

But in the face of the alpha variant, data from the Institute of Public Health in England suggests that two doses of the Pfizer vaccine their efficiency is reduced to 93%. AND against the delta it falls to 88%. The AstraZeneca vaccine is also affected in the same way.

Their data suggests that two to four weeks after someone receives a second dose of Pfizer, they have around 87% less likely to have symptoms of covid-19 when exposed to the delta variant. After four to five months, that number drops to 77%.

4-Your immune system

It should be noted that the above figures refer to the average reduction in risk in a population.

A person’s individual risk will depend on their own level of immunity and other specific factors. Usually, good immune status declines with age.

Long-term medical conditions can also affect our response to vaccination. So, the elderly or people with weakened immune systems may have lower levels of immunization-induced protection, or they may see their protection diminish more quickly.

It should also be remembered that the most clinically vulnerable were vaccinated first, perhaps more than six months ago, which may increase their risk of contracting an infection due to reduced protection.
