Smoking does not kill you when you get vaccinated. There is no clear clinical regulation that lists smoking as a contraindication to the new crown vaccination, and there have been no cases of death due to smoking among the current vaccinated population, but it is not recommended to smoke within 1 week after the new crown vaccination. Harmful substances contained in cigarettes, such as nicotine, aldehydes, nitrogen compounds, etc., can directly or indirectly damage the human respiratory tract, heart and other organs, especially affecting the respiratory protection function, leading to an increase in the prevalence of respiratory infectious diseases. After receiving the new crown vaccine, some people may experience redness, swelling and hardness of the skin at the injection site within 1 week, as well as generalized weakness, diarrhea, allergies and other adverse reactions. Smoking at this time may stimulate the human body and trigger or aggravate the adverse reactions, so it is not recommended to smoke within 1 week after receiving the new crown vaccine. Prolonged smoking may also cause irreversible damage, which will increase the secretion of gastric acid, increase the chance of ulcer disease, and in some people, may also induce cancer. Therefore, although smoking will not kill you after receiving the New Crown Vaccine, it is recommended to quit smoking or reduce the frequency of smoking as much as possible from a health point of view. The vaccine is not 100% effective in preventing pneumonia, so even if you have received the vaccine, you should take good protective measures, pay attention to the correct wearing of masks, wash your hands often, open windows more often to ventilate the air, try not to go to densely populated places, and keep a certain social distance from others. Pay attention to balanced diet and nutrition, eat less spicy, stimulating, greasy food, less late at night, adhere to the daily moderate exercise, in order to increase the body’s resistance to prevent infection.
