What are the risks of contracting the emerging corona virus "Covid-19" again?
How to reduce arm pain after receiving the Corona vaccine?
What are the reasons why women suffer more side effects from the Corona vaccine than men?
We start with the first question, “What are the risks of contracting the Coronavirus again?”, And the direct answer is that the hypothesis of infection with the same strain of Coronavirus again seems very unlikely, especially during the six months following the first infection.
But acquired immunity seems insufficient to be immune to the Brazilian or South African strain, according to a report by Florion Gautier, published in the French Liberation newspaper.
The writer said that confirmed cases of renewed infection with the Coronavirus - whose scientific name is SARS-CoV-2 - during the year 2020 were very rare.
The main reason, according to scientists, is the acquired immunity after exposure to the virus for the first time.
Experiments conducted over the past months in many laboratories around the world confirmed this hypothesis, as after long months of infection with the Coronavirus, the blood of previous patients remains a carrier of antibodies that are able to combat and neutralize the Corona virus.
This immunity is attributed to the fact that the virus to which the individual is exposed for the second time does not have changed much compared to what it was the first time.
But these same studies showed the difficulty that antibodies face in neutralizing some strains, especially those identified in South Africa and Brazil, which carry the E484K gene mutation.
Whereas, cases of renewed infection with the British strain known as "B.1.1.7" B.1.1.7 remain rare so far.
The writer says that the currently available data on the extent of the seriousness of the Covid-19 virus for those infected for the second time remains scarce and unclear.
But the hypothesis that the acquired immunity during the first infection remains insufficient to prevent the renewal of infection with the virus, although it will in all cases contribute to its weakening and thus alleviating the severity of the symptoms that appear on the patient.
How to relieve arm pain after receiving the Corona vaccine?
The most common side effect after vaccination is pain in the arm where the vaccine was injected.
Some people report dull pain similar to what happens after receiving the flu shot, while others said they cannot move their arm due to the pain.
Here we offer tips for relieving arm pain after receiving the Korna vaccine, according to a report by Julia Naftoline published by the American Insider website:
1- Moving the arm
"This sensation is caused by the immune cells' response to the vaccine," said Dr. Daniel Summers, a pediatrician in Maine.
Since the arm is where the vaccine was injected, immune cells rush to that area and cause it to become inflamed, and the area becomes red and swollen.
Moving your arm throughout the day, whether through exercise or moving your arm around the living room, can relieve arm pain.
2- A piece of cloth and cold water
According to the U.S. Centers for Disease Control and Prevention, you can cool the injection area with a clean cloth dampened in cold water.
3- Drink plenty of fluids to stay hydrated
4- Take a break
5- Analgesics
Dr. Libby Roy, a resident physician in internal medicine in New York City, suggested using an ice pack and an over-the-counter pain reliever like Tylenol or Ibuprofen because they reduce inflammation.
It can be used after your vaccination appointment, Roy said, unless your doctor has previously authorized you to take it.
On the other hand, we must refer to the symptoms that you may feel after receiving the Corona vaccine, which means that your immune system is working the way it is supposed to work, according to experts who advise trying to avoid painkillers to ensure the strongest possible immune response, which is what the Harvard College THH website stated. Harvard TH Chan School of Public Health.
Experts say that although it is not known whether painkillers can interfere with the effectiveness of Covid-19 vaccines, it is possible, so it is best to avoid pain relievers if you can.
According to a study published in the medical journal Chest, the painkillers may lower the level of antibodies after the vaccination.
Do not massage the arm
On the other hand, it is not recommended to massage the arm, although moving the arm helps to reduce inflammation in this area faster, on the other hand, simply massaging the place of vaccination with your hand will aggravate the inflammation and pain.
Summers added, "Massaging the vaccine injection site will not really have any negative effects, but because doing so may cause the vaccine to spread to a larger area that will become inflamed afterward when the immune system responds, so the pain area expands."
According to Summers, the arm pain subsides a day or two after receiving the vaccine.
It should be noted that the flu-like symptoms should disappear after a few days, and if during them they do not go away, you should contact your doctor.
4 reasons why women suffer more side effects from the Corona vaccine than men
Side effects of the "Covid-19" vaccine include fever, chills, and pain at the injection site.
Women report these side effects more often than men, according to a report by Barbara Sadik on the healthy site.
Sadik quotes Betsy Koekle, a family medicine specialist at Northwell Health in Levittown, New York, as saying that women's bodies are hormonally and genetically different from men's bodies, respond differently to different medical interventions, and interact differently with most vaccines.
Here are 4 possible reasons why women may report more side effects than men after receiving the Corona vaccine:
Women are more likely than men to report side effects.
Hormones may affect the immune system, and Dr. Quickle says the female hormone estrogen generally boosts and influences the reaction of the immune system.
On the other hand, the male hormone testosterone tends to act as an immunosuppressant.
Women may have healthier immune systems, which leads to more Covid-19 vaccine side effects.
"We have noticed that side effects are more common in young people after the second injection and occur more frequently in younger people who have a healthier immune system," says Dr. Daniel Kuritzks, chair of the Department of Infectious Diseases and Women at Brigham Hospital and a professor at Harvard Medical School in Boston.
