• If people who are vaccinated develop COVID-19 they are less likely to be hospitalized than people who are not vaccinated, but they can still get caught.
  • In the UK, research has shown that 0.2% of the population (or 500 per person) has an advanced infection after being fully vaccinated.
  • Factors influencing this may include vaccine type, time after vaccination, and COVID-19 vaccines.

Two weeks after the second dose of COVID-19 vaccine, the protective effects of the vaccine will be highest. At this point, you are completely embedded. If you still get COVID-19 from that point on, you will have a “progression” infection. Overall, advanced infections are similar to those of common COVID-19 infections in uninvigorated individuals, but there are some differences. Here’s what to look for if you’ve had two blows.

COVID Symptoms According to the study, the five most common symptoms of an advanced infection are headache, runny nose, sneezing, sore throat, and loss of smell. Some of them are the same symptoms as people who have not had the vaccine experience. If you have not been vaccinated, three of the most common symptoms are headache, sore throat and runny nose.

However, the other two most common symptoms of non-vaccination are fever and persistent cough. These “classic” symptoms of COVID-19 are less common after your blows. One study found that people with advanced infections were 58% less likely to get the fever than people who were not vaccinated. Rather, it has been said that many people with COVID-19 feel cold after taking the vaccine.

If vaccinated people develop COVID-19 they are less likely to be hospitalized than uninserted people. It is likely that there will be fewer symptoms in the early stages of the disease and less development of long-term KOVID.

The reasons why the vaccinated people are more susceptible to the disease are that vaccines, if they do not block the infection, seem to cause infected people to have fewer virus particles. However, it has not yet been confirmed.

What creates the risk?

In the UK, research has shown that 0.2% of the population (or 500 per person) has an advanced infection after being fully vaccinated. But not everyone has the same risk. There seem to be four things that protect you with the vaccine.

The first is the exact type of vaccine you received and the relative risk reduction that each type offers. Relative risk reduction is a measure that reduces the risk of someone developing a COVID-19 compared to someone who has not been vaccinated.

Clinical trials found that the Moderna vaccine reduced the risk of COVID-19 being symptomatic for one person by 94%, while the Pfizer vaccine reduced the risk by 95%. Johnson & Johnson and AstraZeneca vaccines did not have such good results, reducing this risk by about 66% and 70%, respectively (although the protection offered by the AstraZeneca vaccine rises to 81% if there is a longer interval between doses).

2. Time since vaccination

These images do not paint the whole picture. It is becoming increasingly clear that long-term vaccination is also important and is one of the reasons for the growing intensity of discussions about booster vaccines.

Early research, pre-printed (still unreviewed by other scientists) suggests that Pfizer vaccine protection declined within six months of receiving the vaccine. Another prepress from Israel suggests the same. It is too early to know what happens to the effectiveness of the vaccine in a double vaccine beyond six months, but it is likely to be further reduced.

Another important factor is the variant of the virus you are facing. The above risk reductions were largely calculated by examining vaccines against the original form of coronavirus.

In contrast to the alpha variant, data from Public Health England suggest that they are slightly less likely to protect two doses of the Pfizer vaccine, reducing the risk of COVID-19 symptoms by 93%. Against the delta, the level of protection falls even further, to 88%. The AstraZeneca vaccine also affects this way.

The COVID Symptom Study supports all of this. His data suggests that within two to four weeks of receiving your second Pfizer jab, you experience about 87% fewer COVID-19 symptoms when faced with a delta. After four or five months, this figure drops to 77%.

It is important to remember that the above figures refer to a reduction in the average risk to the population. Your risk will depend on your immunity levels and other specific factors in the person (e.g., you are exposed to the virus, which can be determined by your job).

Immune fitness usually decreases with age. The long-term health condition can also damage our response to the vaccine. The elderly or people at risk for the immune system may therefore have a lower level of protection from vaccines against COVID-19 or may see their protection reduced more rapidly.

It should be remembered that the most clinically vulnerable were first vaccinated, perhaps more than eight months ago, which may lead to a reduction in protection and an increased risk of developing an infection.

Do you have to worry?

Vaccines still greatly reduce the chances of COVID-19. They also further protect against hospitalization and death.

However, it is to see progressive infections, and the concern is that if vaccine protection falls over time, as they suspect, they can increase. Therefore, the UK government intends to provide a dose of the most vulnerable, and is also looking at whether it should be given to developers more broadly. Other countries, including France and Germany, already plan to offer boosts to groups at higher risk for COVID-19.

Pushers are also used, but should not be interpreted as vaccines that do not work. In the meantime, it is essential to promote the vaccine to all those who have not yet been vaccinated.
