Vaccine, exemption only for a few patients with pre-existing pathologies: here are which ones

by admin

Most adults, regardless of their condition, can get vaccinated, experts say. There are very few pathologies or conditions in the presence of which exemption is recommended. Studies by American researchers of the CDC (Centers for Disease Control and Prevention) reveal this. Dr David Dowdy, an epidemiologist at the Johns Hopkins Bloomberg School of Public Health, said that Extensive and growing data on the three coronavirus vaccines show that there are no immediate health problems or side effects for most people with pre-existing medical conditions.

The current guidance from the U.S. Centers for Disease Control and Prevention states that two-dose mRNA vaccines and the one-dose Johnson & Johnson vaccine are safe for almost any patient. The only major contraindication to vaccines may be at most a severe allergic reaction to the first dose. In such cases, the person is advised to consult a doctor and stop the second dose. “By allergic reaction we do not mean what most vaccinates have had and that is pain at the injection site or a rash, but we are talking about anaphylactic shock – he said. Dowdy – data indicates that this severe allergy is rare so far and less than one in 1 million suffers from it. ‘

Dr. Jeff Linder, chief of general internal medicine and geriatrics at Northwestern University Feinberg School of Medicine, clarified that this severe allergic reaction is likely triggered by polyethylene glycol (PEG), a component found in vaccines. However it assures “an allergy to this component is rather rare. Only in the case of a documented allergy to this component of the vaccine should a vaccination exemption be granted. ‘

Overall, vaccines are safe even for people with compromised immune defense. The CDC, on the other hand, recommends some extra precautions only in a few cases. For example, people with a history of heparin-induced thrombocytopenia (HIT) are advised to choose an mRNA vaccine. According to the CDC, women over the age of 50 face a potential risk of thrombosis with thrombocytopenia syndrome (TTS) if they choose the Johnson & Johnson vaccine. The agency currently recommends not getting the vaccine immediately in only two cases. If a person is currently suffering from Covid or has been in contact with a sick person, it is advisable to get the vaccine only at the end of the quarantine period. If a patient is receiving monoclonal antibodies or plasma after Covid infection they are advised to postpone the vaccine appointment after 90 days. However, Dowdy said neither scenario should prevent someone from getting the vaccine. «People ask: “sand I have contracted Covid in the past do I have to get the vaccine? The answer is yes, the vaccine adds extra protection».

Dr. Jay Bhatt, MD, an instructor at the University of Illinois School of Public Health, added that special attention should be paid to patients who are awaiting an organ transplant, who have recently received an organ transplant or who are receiving treatment for metastatic cancer. Those patients should consult with their doctors and determine the most suitable time to get vaccinated.
