It typically takes a few weeks for the body to build immunity (protection against the virus that causes COVID-19) after vaccination. That means it’s possible a person could be infected with the virus that causes COVID-19 just before or just after vaccination and still get sick.
For now, the CDC recommends that people not assume they are completely immune to infection after having been vaccinated. Overall, both vaccines provided about 95% protection in clinical trials — so a small number of people might still catch the virus even after two shots.
While the COVID-19 vaccine isn’t necessary to fly yet, some high-risk nations require specific immunizations to enter the country. For example, it’s typical for many countries in Latin America, Asia and Africa to require the Yellow Fever vaccine.
You should get your second shot: for the Pfizer-BioNTech 3 weeks (or 21 days) after your first shot, for the Moderna 1 month (or 28 days) after your first shot.
Посмотреть полный ответ At the time of preparing this Q&A, there are no peer-reviewed studies that have evaluated the risk of SARS-CoV-2 infection associated with smoking. However, tobacco smokers (cigarettes, waterpipes, bidis, cigars, heated tobacco products) may be more vulnerable to contracting COVID-19, as the act of smoking involves contact of fingers (and possibly contaminated cigarettes) with the lips, which increases the possibility of transmission of viruses from hand to mouth. Smoking waterpipes, also known as shisha or hookah, often involves the sharing of mouth pieces and hoses, which could facilitate the transmission of the COVID-19 virus in communal and social settings.
SARS-CoV-2 RNA has also been detected in other biological samples, including the urine and feces of some patients. One study found viable SARS-CoV-2 in the urine of one patient. Three studies have cultured SARS-CoV-2 from stool specimens. To date, however, there have been no published reports of transmission of SARS-CoV-2 through feces or urine.
There is some evidence that COVID-19 infection may lead to intestinal infection and be present in faeces. However, to date only one study has cultured the COVID-19 virus from a single stool specimen. There have been no reports of faecal−oral transmission of the COVID-19 virus to date.
We still do not know if a pregnant woman with COVID-19 can pass the virus to her fetus or baby during pregnancy or delivery.
People should NOT wear masks when exercising, as masks may reduce the ability to breathe comfortably. Sweat can make the mask become wet more quickly which makes it difficult to breathe and promotes the growth of microorganisms.
• When cooking and preparing food, limit the amount of salt and high-sodium condiments (e.g. soy sauce and fish sauce). • Limit your daily salt intake to less than 5 g (approximately 1 teaspoon), and use iodized salt. • Avoid foods (e.g. snacks) that are high in salt and sugar. • Limit your intake of soft drinks or sodas and other drinks that are high in sugar (e.g. fruit juices, fruit juice concentrates and syrups, flavoured milks and yogurt drinks). • Choose fresh fruits instead of sweet snacks such as cookies, cakes and chocolate.
People of all ages can be infected by the new coronavirus (COVID19). Older people, and people with pre-existing medical conditions (such as obesity, asthma, diabetes, heart disease) appear to be more vulnerable to becoming severely ill with the virus. WHO advises people of all ages to take steps to protect themselves from the virus, for example by following good hand hygiene and good respiratory hygiene.
Experts hypothesize that the virus homes in on those cells, disrupting the pathway for the neurons to get to their destination in the brain. When that happens, people lose their sense of smell. And smell is directly linked to how a person experiences taste.
The incubation period of COVID-19, which is the time between exposure to the virus and symptom onset, is on average 5-6 days, but can be as long as 14 days. Thus, quarantine should be in place for 14 days from the last exposure to a confirmed case.

Pregnant women or recently pregnant women who are older, overweight, and have pre-existing medical conditions such as hypertension and diabetes seem to have an increased risk of developing severe COVID-19. When pregnant women develop severe disease, they also seem to more often require care in intensive care units than non-pregnant women of reproductive age. Due to changes in their bodies and immune systems, we know that pregnant women can be badly affected by some respiratory infections. It is therefore important that they take precautions to protect themselves against COVID-19, and report possible symptoms (including fever, cough or difficulty in breathing) to their healthcare provider.
“In other words, a vaccinated person might still be able to spread the virus, even if they don’t feel sick.” Until researchers can answer that question, Frieden said, wearing masks is the safest way for vaccinated people to protect those around them. 2 дня назад
