Question: How Many Vaccines Are There?

Are you immune to COVID-19 if you get it once?

Research is still ongoing into how strong that protection is and how long it lasts.

WHO is also looking into whether the strength and length of immune response depends on the type of infection a person has: without symptoms (‘asymptomatic’), mild or severe.

Even people without symptoms seem to develop an immune response..

What happens when you get the coronavirus disease?

People with COVID-19 generally develop signs and symptoms, including mild respiratory symptoms and fever, on an average of 5-6 days after infection (mean incubation period 5-6 days, range 1-14 days). Most people infected with COVID-19 virus have mild disease and recover.

When is World Immunization Week?

World Immunization Week – celebrated in the last week of April (24 to 30 April) – aims to promote the use of vaccines to protect people of all ages against disease. Immunization saves millions of lives every year and is widely recognized as one of the world’s most successful and cost-effective health interventions.

Can the coronavirus spread via feces?

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.

Can the coronavirus disease spread through sewage?

There is no evidence that the COVID-19 virus has been transmitted via sewerage systems with or without wastewater treatment.

What is the recovery time for the coronavirus disease?

Using available preliminary data, the median time from onset to clinical recovery for mild cases is approximately 2 weeks and is 3-6 weeks for patients with severe or critical disease.

Is the coronavirus disease a pandemic?

COVID-19 can be characterized as a pandemic. This is due to the rapid increase in the number of cases outside China over the past 2 weeks that has affected a growing number of countries.

Can COVID-19 be transmitted through feces or urine?

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.

Can drinking alcohol help in preventing COVID-19?

Alcohol does not protect against COVID-19; access should be restricted during lockdown.

Is there a vaccine for other disease that can be use to treat COVID-19?

Currently, there is no evidence that any existing vaccines will protect against COVID-19.However, scientists are studying whether some existing vaccines – such as the Bacille Calmette-Guérin (BCG) vaccine, which is used to prevent tuberculosis – are also effective for COVID-19. WHO will evaluate evidence from these studies when available.

Can COVID-19 be transmitted through food?

There is currently no evidence that people can catch COVID-19 from food. The virus that causes COVID-19 can be killed at temperatures similar to that of other known viruses and bacteria found in food.

Who is most at risk for COVID-19?

The COVID-19 virus infects people of all ages. However, evidence to date suggests that two groups of people are at a higher risk of getting severe COVID-19 disease. These are older people; and those with underlying medical conditions. WHO emphasizes that all must protect themselves from COVID-19 in order to protect others.

Can coronavirus disease spread through raw food?

As a general rule, the consumption of raw or undercooked animal products should be avoided. Raw meat, raw milk or raw animal organs should be handled with care to avoid cross- contamination with uncooked foods.

Can babies get the coronavirus disease?

We know it is possible for people of any age to be infected with the virus, but so far there are relatively few cases of COVID-19 reported among children.

What is the theme for the 2020 World Immunization Week?

The theme this year is #VaccinesWork for All and the campaign will focus on how vaccines – and the people who develop, deliver and receive them – are heroes by working to protect the health of everyone, everywhere.

What is the vaccine procurement process?

Vaccine procurement describes the process of acquiring vaccines domestically or internationally, using specific procurement procedures and/or mechanisms. The procurement of vaccines is a complex process that requires specialized knowledge to ensure the timely and cost-effective supply of high-quality products.

How dangerous is COVID-19?

Although for most people COVID-19 causes only mild illness, it can make some people very ill. More rarely, the disease can be fatal. Older people, and those with pre- existing medical conditions (such as high blood pressure, heart problems or diabetes) appear to be more vulnerable.

Do smokers get more severe symptoms of COVID-19 if infected?

Smoking any kind of tobacco reduces lung capacity and increases the risk of many respiratory infections and can increase the severity of respiratory diseases. COVID-19 is an infectious disease that primarily attacks the lungs. Smoking impairs lung function making it harder for the body to fight off coronaviruses and other respiratory diseases. Available research suggests that smokers are at higher risk of developing severe COVID-19 outcomes and death.
