Covid Vaccine Side Effects You Should Know About, According to the CDC

The high incidence of Covid-19 and influenza A in recent weeks has brought back into the news some social recommendations and exceptional measures that already seemed outdated and which were not present in daily activities during the last two years. The return of masks to health centers, which until now have been voluntary in public areas, is a symptom of this, and prevention remains important. when it comes to preventing complications caused by the virus that caused the global pandemic in the spring of 2020.

Although successive mutations of the virus led to influenza and most of the population has been vaccinated, covid still exists and this campaign has also encouraged people to get the vaccine from health authorities. Nowadays, in addition, the most noticeable part of the symptoms does not occur so often. In any case, it doesn’t hurt to remember them if you have doubts about possible infection, in addition to restore the habit of taking the test in this situation.

The Centers for Disease Control and Prevention, known as CDC, reminds us of two interesting facts, especially for high-risk patients. “You should get an updated Covid-19 vaccine even if you have already had it. “Getting vaccinated after you have recovered from a Covid-19 infection gives you additional protection against the virus that causes the disease.” Of course, the CDC indicates that the ideal is to wait three months after the patient tests negative and is confirmed recovered.

On the other hand, the CDC clarifies that “people who have already had Covid-19 and are not vaccinated after recovery are more likely to be reinfected with Covid-19 than those who are vaccinated after recovery.”

Side effects of the Covid vaccine: degrees and frequency of occurrence

Side effects of the Covid-19 vaccine may vary depending on each person. It is normal that they do not affect daily activities, they are mild and disappear after a few days, as happens with other vaccines. There are a number of recommendations that can effectively mitigate them and at the same time avoid common mistakes. For example, it is not recommended to take pain relievers or medications such as ibuprofen, aspirin (for people 18 and older only), or acetaminophen before getting the vaccine to avoid side effects. To relieve pain in the arm where the injection is given, you can apply a clean, cool, damp cloth to the area. Additionally, you must keep your hand active. If you have a fever, you need to drink water.

However Although they are rare, more serious cases of adverse reactions have stated by the CDC itself.

Anaphylaxis after vaccination

Index cases are approximately 5 per million doses administered. This is a serious allergic reaction that can occur after any vaccine.

Guillain-Barre syndrome (GBS) after vaccination

GBS is a rare disease in which the immune system damages neurons and causes muscle weakness, including paralysis. GBS was observed predominantly among people 50 years of age and older.

Data from the Vaccine Safety Data Link (VSD) explains that GBS levels during the first 21 days after administration of the J&J/Janssen covid-19 vaccine were 21 times higher than after the Pfizer-BioNTech or Moderna Covid-19 mRNA vaccines.

These observations contributed to the Advisory Committee on Immunization Practices (ACIP) recommendation that mRNA vaccines be preferred against Covid-19.

Myocarditis and pericarditis after vaccination against covid

They are rare after the Covid-19 vaccine. Myocarditis is inflammation of the heart muscle, and pericarditis is inflammation of the outer layer covering the heart. Most patients with myocarditis or pericarditis responded well to medication and rest after Covid-19 vaccination.

Thrombosis with thrombocytopenia (TTC) after vaccination

Are very rareAlthough serious, cases of this syndrome after the vaccine: 4 per million doses of J&J/Janssen. TTC causes blood clots to form in large blood vessels and reduce platelet counts. This discovery also prompted ACIP to recommend mRNA vaccines (Pfizer and Moderna) against Covid-19.
