Answer: Is it necessary to get a vaccine for recovered new crown patients?

Long press the QR code to receive the public's suspicion about the new crown vaccine at the beginning of the year.
Recently, with the development of the Guangdong epidemic, people's demand for vaccines is becoming more and more urgent
.

Healthy people are vaccinated in order to resist the virus.
So those who have unfortunately been infected with the new crown but have recovered will be immune to them for life like they have been infected with chickenpox.
Is there any need to get vaccinated? There are various opinions on the Internet, and some relevant reports are published on the BIO SPACE website for your reference, as follows
.

01 A study published in Brazil in March of 33 patients with COVID-19 (30 of whom were medical staff) repeatedly infected with COVID-19 stated that the second infection was “often more severe”, and one patient who relapsed at the time of follow-up had passed away
.

The study found that after experiencing the first infection, the patient's IgG or immunoglobulin G antibody level was significantly reduced
.

This fact provides a basis for the speculation that "people with weak antibody responses are more likely to be infected by the virus again after being infected with SARS-CoV-2
.
"
02 This study was conducted on more than 3,000 healthy members of the US Marine Corps between 18 and 20 years old
.

Studies have shown that previous new coronavirus infections cannot prevent re-infection.
This is because the more transmissible mutant strains found so far, such as B.
1.
1.
7 and B.
1.
617, are not the main types of strains that caused the infection before
.

In other words, rehabilitation can only mean that you have developed antibody immunity to the previous strain, but your body has no related antibodies to the new variant strains currently circulating.
Take a step back.
According to research findings, even in the face of the same strain, recovery The person also has a high probability of being infected again
.

In this study, the researchers finally recovered the virus they used for experimental culture, which implies that the risk of transmission is still quite high
.

03 The Centers for Disease Control and Prevention (CDC) issued a new report in May that showed that between January 1 and April 30, only 0.
01% of vaccinated Americans experienced breakthrough infections
.

According to the CDC, nearly 101 million people were fully immunized at the end of April, of which only 10,662 breakthrough cases were reported.
Of these reported cases, only 2% of the cases died
.

This implies that the vaccine injection has also strongly curbed the progression of the new crown disease
.

04 The study was conducted on 51 British medical staff.
About half of the people who participated in the study had been diagnosed with SARS-COV-2 infection.
After receiving a single dose of Pfizer/BioNTech vaccine, they showed a higher immune response.
Immune response after vaccination in uninfected people
.

To focus on the key points, people who have been infected with the new crown must be vaccinated.
There is no benefit if the vaccine is not given
.

Even people who have recovered after being infected with the new crown, exposed to the virus environment, still have a high probability of being infected again
.

Among them, the symptoms of the young people's re-infection may be mild, and they do not even realize that they are re-infected, so that they can further spread it to other people who are susceptible to infection
.

Natural infections can help a person gain a series of immunity, and vaccines can continue to induce high levels of antibodies
.

If the vaccine is not accepted, the chance of re-infection has great variability.
In the Marine Corps study, the quantity and quality of the antibodies produced by the first infection of young people are directly linked to the second infection; while for the elderly Or for other people who are not so immune, the number of antibodies produced by the first infection is not enough to fight the second infection
.

Although in general, re-infection within a few months after the initial infection of the new crown is not common, it is necessary to consider that the risk of re-infection is positively correlated with time
.

Vaccines give people far more defenses against viruses than natural immunity, and it also responds better to newly generated mutant strains
.

But will things be over after the vaccine? No, even if vaccinated, not everyone can produce an effective immune response
.

In places with high population mobility and large populations, it is still necessary to protect yourself and wear masks
.

Finally, I hope that the epidemic situation in Guangzhou will get better and everyone will spend the past few years in good health
