People who completed their Covid-19 vaccination regimen or who received a dose of the vaccine reported fewer symptoms and over a “shorter period” compared to unvaccinated people, according to an English study.
- 4 million users have recorded their symptoms on the English application.
- 53.3 million patients (or 78.6% of French people) have an initial vaccination schedule completed according to Health Insurance.
The virus is evolving and so are the symptoms it causes… A UK app titled Zoe Covid Study has collected data on the disease since the start of the pandemic and has looked in particular at the symptoms observed when people contracted the virus. The data was analyzed by scientists from the King’s College of London or the Universities ofHarvard and of Stanford.
The symptoms of Covid-19 do not differ much depending on the number of doses of vaccine received
It appears that depending on whether or not one is vaccinated, with one or more doses, and whether one has been infected with the first historical variants of the virus or Omicron and its current sub-variants which are still progressing in France, the symptoms developed are not the same.
In fact, the symptoms most frequently observed this fall in people on the complete vaccination schedule are, in order: sore throat, stuffy and runny nose, persistent cough and headache. The English also noted that vaccinated people could sneeze, which is not the case for unvaccinated people.
The ranking changes with a single dose of vaccine as headaches take first place, followed by runny nose, sore throat, sneezing and persistent cough. The unvaccinated meanwhile have quite similar symptoms except for the fever which is added to the list which sees the headache coming in first position followed by sore throat, runny nose, and fever therefore, in 4th position and finally persistent cough.
In a 2021 study by the Centers for Disease Control and Prevention, participants who received one or two doses of the Covid vaccine already had about a 60% lower risk of developing symptoms such as fever, compared to unvaccinated people. The study also showed that vaccinated participants spent an average of two to six days less in bed than unvaccinated people.
Symptoms of Covid-19 are non-specific
The symptoms recorded at the start of the pandemic differ with the evolutionary variants of the virus. Indeed the Zoe application has highlighted a result common to the three groups: a significant reduction in symptoms “traditional” of the initial strain of the virus, such as shortness of breath (in 30th position) and loss of smell (in 9th position).
It is therefore difficult to dissociate, from the symptoms, the Covid-19 from the flu (or from a simple cold) which nevertheless have significant differences.
This is why it is always advised to get tested If in doubt. And to get vaccinated since virus circulation is still high and with it, the risk of developing a serious form of Covid.
