Is it dangerous to get vaccinated when you have already had the coronavirus?

VERIFIERS WITH INSERM – A message received by the editorial staff of LCI.fr worries about the possible danger of a vaccine against Covid-19 for people already infected. We are responding with Béhazine Combadière, research director at Inserm.

Anxious to fight against false information on a daily basis, the Verifiers team has forged a partnership with the National Institute for Health and Medical Research (Inserm). Objective: to interview the most seasoned researchers and answer the questions Internet users have about the coronavirus and vaccination. In this first episode, we deal with Emmanuelle’s question, sent to the dedicated email address [email protected].

She wonders about the delay before getting vaccinated for a person who has already had the virus. And on the possibility of a vaccine “dangerous” for an asymptomatic who is unaware of having contracted the disease.

Can’t get vaccinated if you’ve caught Covid-19?

Since the start of the epidemic, more than three million people have contracted Covid-19 and have recovered from it. A number that will double according to the latest calculations by the Institut Pasteur, for whom 17% of the population in metropolitan France has contracted the disease. So many people who therefore do not a priori need to receive one of the precious doses. “From an immunological point of view, it does not seem to me that the vaccination of people who have already contracted the virus is a priority”, confirms Béhazine Combadière, research director at Inserm. It is in this spirit that the Haute Autorité de Santé (HAS) published a first opinion on the issue on December 18. Observing that the data did not allow “to know if there is any benefit in vaccinating people who have already been infected”, the public authority considered that there was “no need to systematically vaccinate people who have already developed a symptomatic form of Covid-19”. However, the administration backed down. And she now recommends a single dose, taken after three months.

Why this delay, which worries the Internet user who contacted us? “This is the time for the immune memory to be put in place”, answers the expert from INSEE. “It takes a while to create this memory and we consider, through observation of viruses in general, that this time frame is three months.” Reason why people who have tested positive are “considered to be protected for at least three months by post-infectious immunity”, writes the HAS.

This delay is therefore not linked to a potential dangerous character. “It is absolutely not contraindicated to be vaccinated after contamination”, repeats the researcher at the center of immunology and infectious diseases, “even if we have just had it or if we have had asymptomatic forms”. At LCI.fr, she explains in fact that an immune response cannot be harmful. “Once the body sees the virus, and has a response, the vaccine just revives the immune system by pumping the virus back to it.”

Why a three-month delay?

If it’s not dangerous, why stick to this three-month deadline? Quite simply because France does not have enough supplies. “For the healthy population which has already had the virus, given the current situation of a lack of doses, there is no urgent need to be vaccinated”, summarizes the researcher.

However, there is a downside. The long-term immunity of those previously infected is not known. “The immune responses after infection are variable and more or less important. We must be sure to achieve good levels of immunity”, underlines the research director. Reason why, after having estimated last December that there was “no need to systematically vaccinate” This public, the Haute Autorité de Santé has changed its recommendations.

Can we therefore combine “natural” protection with that of the vaccine? “Absolutely”, answers our interlocutor. The single dose of vaccine will simply act as a booster. “It is the same principle as the recall every ten years”, she advances, pedagogically. “The immune system is asked to remember how it fights the virus. It’s good for immune memory.” And to take a very ordinary example: “It’s like looking at a photo at regular intervals, to make sure the memory of the moment stays intact.”

the number of hospitalizations on a high plateau, the positivity rate on the rise

The coronavirus epidemic is inexorably continuing its progression in France. While an outbreak of contamination cases has prompted the authorities to place 20 departments under enhanced surveillance, the number of patients in the hospital is around 25,000, including some 3,400 in intensive care, according to data published by Public Health France, Saturday February 26. The positivity rate continues to increase and now reaches 7.2%.

We now count 24,995 people infected with the coronavirus in hospitals, against 25,130 Friday. A week earlier, they were 25,269. Of these nearly 25,000 patients, 1,007 have been admitted to hospital in the past 24 hours, against 1,634 on Friday. As regards the most severe cases of the disease, 3,445 patients (including 208 transferred in the last 24 hours), are placed in intensive care units, against 3,445 on Friday.

Some 24,000 (23,996) people have been diagnosed positive for the virus (compared to 25,207 on Friday) and the positivity rate (the number of positive people out of all those tested) continues to increase, at 7.2%, against 7.1% on Friday and 6.1% on Saturday, February 20.

In total, the epidemic caused 186 deaths on Saturday out of a total of 86,332 victims in France since the start of the spread of the virus. More than 3 million people will soon have received at least one dose of vaccine: there were 2.918 million on Friday. Among those vaccinated, 1.561 million received the two doses of the anti-Covid serum, as part of the vaccination campaign.

Coronavirus pandemic. Most relevant for February 28

439 people became victims of coronavirus infection per day, their total number, according to the headquarters, is 85.7 thousand.This is less than the estimates of Rosstat, which only from April to November last year counted more than 116 thousand deaths. The difference is explained by a different calculation methodology: Rosstat includes in its statistics people who have been diagnosed with coronavirus after death, as well as deaths from other diseases against the background of COVID-19.

“Vedomosti”, citing sources close to the Moscow government and the presidential administration, reported that in April the epidemiological situation in the capital may worsen due to the appearance of those infected with the “British” strain. The Moscow mayor’s office responded to these messages and said that the city has deployed a sufficient number of beds for patients, and the doctors are provided with everything necessary.

  • According to the chief freelance epidemiologist of the Ministry of Health Nikolai Briko, there is no need to expect a new wave of the epidemic in the near future. A new increase in the incidence will happen closer to the next autumn-winter.

The Argentine economy will contract by 10% in 2020

The Argentine economy will contract by 10% in 2020

Cairo – Middle Gate | Friday 26 February 2021, 09:08 AM

The Argentine economy recorded a contraction of 10% in 2020 compared to 2019, after it was severely affected by the repercussions of the Corona virus, according to initial official estimates.

In December, GDP recorded a growth of 0.9% compared to the previous month, which is the eighth monthly growth recorded after the decline in April (-25.4%) and May (-20%), which were characterized by a near paralysis of activity related to restrictive health measures. The industrial sector did not gradually resume its activities before the third quarter of the year, despite restrictions on the movement of residents.

These projections are only estimates, as 2020 GDP growth is not officially announced until March. It is better than that contained in the budget bill in September. The government at the time expected a GDP decline of 12.1% in 2020.

Last year, only two sectors witnessed growth: financial intermediation (2.1%) and electricity, gas and water (0.8%), according to data from the National Institute of Statistics and Census. All other sectors saw a setback. The most significant decline in growth was recorded in the hotel and restaurant sector, with a collapse of 48.6%.

For three years, Argentina has been witnessing an economic recession and a decline in the value of its Argentine peso, and since a few years ago, inflation rates are among the highest in the world. Inflation rate reached 36.1% in 2020 and 53.8% in 2019, in record numbers since 1991.

The poverty rate reached 40.9% of the population during the first quarter of 2020, which is among the worst rates recorded in the country’s history, according to the National Institute of Statistics. The percentage of people suffering from extreme poverty, meaning the level of poverty that does not allow access to even basic food needs, reached 10.5% of the population.
