How effective is the Janssen COVID-19 vaccine?
A single dose of Janssen Ad26.COV2.S was found in clinical trials to have an efficacy of 66.9% against symptomatic moderate and severe SARS-CoV-2 infection.
How old do you have to be to get the AstraZeneca vaccine?
The vaccine is not recommended for persons younger than 18 years of age pending the results of further studies.
What is the interval between doses of the Sinopharm COVID-19 vaccine?
WHO recommends an interval of 3–4 weeks between the first and second dose. If the second dose is administered less than 3 weeks after the first, the dose does not need to be repeated. If administration of the second dose is delayed beyond 4 weeks, it should be given at the earliest possible opportunity.
What is the Covax initiative for the development of COVID-19 vaccine?
COVAX aims to accelerate the development and manufacturing of COVID-19 vaccines, and guarantee fair and equitable access for every country. COVAX is co-led by the Coalition for Epidemic Preparedness Innovations (CEPI), Gavi and WHO, with UNICEF as a key delivery partner and PAHO as the procurement agent in the Americas.
What is the percentage of people who need to be immune against COVID-19 in order to achieve herd immunity?
See full answer
We are still learning about immunity to COVID-19. Most people who are infected with COVID-19 develop an immune response within the first few weeks, but we don’t know how strong or lasting that immune response is, or how it differs for different people. There have also been reports of people infected with COVID-19 for a second time. Until we better understand COVID-19 immunity, it will not be possible to know how much of a population is immune and how long that immunity last for, let alone make future predictions. These challenges should preclude any plans that try to increase immunity within a population by allowing people to get infected.

Is it safe to take paracetamol before receiving the COVID-19 vaccine?
Taking painkillers such as paracetamol before receiving the COVID-19 vaccine to prevent side effects is not recommended. This is because it is not known how painkillers may affect how well the vaccine works.
Is it safe to take AstraZeneca covid-19 vaccine during breastfeeding?
Vaccination can be offered to breastfeeding women if they are part of a group prioritized for vaccination. WHO does not recommend discontinuation of breastfeeding after vaccination.
Is Sinovac COVID-19 vaccine safe for pregnant women?
In the interim, WHO recommends the use of the Sinovac-CoronaVac (COVID-19) vaccine in pregnant women when the benefits of vaccination to the pregnant woman outweigh the potential risks.
Are people of a particular age vulnerable to coronavirus disease?
People of all ages can be infected by the COVID-19 virus.Older people and younger people can be infected by the COVID-19 virus. Older people, and people with pre-existing medical conditions such as asthma, diabetes, and heart disease appear to be more vulnerable to becoming severely ill with the virus.
What are the organs most affected by COVID‐19?
The lungs are the organs most affected by COVID‐19.
How long does the virus that causes COVID-19 last on surfaces?
Recent research evaluated the survival of the COVID-19 virus on different surfaces and reported that the virus can remain viable for up to 72 hours on plastic and stainless steel, up to four hours on copper, and up to 24 hours on cardboard.
Can I get COVID-19 from eating fresh food?
There is currently no evidence that people can catch COVID-19 from food, including fruits and vegetables. Fresh fruits and vegetables are part of a healthy diet and their consumption should be encouraged.
Who issued the official name of COVID-19?
The official names COVID-19 and SARS-CoV-2 were issued by the WHO on 11 February 2020.
Where was COVID-19 first discovered?
The first known infections from SARS-CoV-2 were discovered in Wuhan, China. The original source of viral transmission to humans remains unclear, as does whether the virus became pathogenic before or after the spillover event.
Can you get COVID-19 from faeces?
The risk of catching the COVID-19 virus from the faeces of an infected person appears to be low. There is some evidence that the COVID-19 virus may lead to intestinal infection and be present in faeces.
What is the body’s first line of defense against pathogens?
The body has many ways of defending itself against pathogens (disease-causing organisms). Skin, mucus, and cilia (microscopic hairs that move debris away from the lungs) all work as physical barriers to prevent pathogens from entering the body in the first place.
Who are at higher risk of developing serious illness from COVID-19?
Older people, and those with underlying medical problems like cardiovascular disease, diabetes, chronic respiratory disease, and cancer are more likely to develop serious illness.
Are smokers more likely to develop severe symptoms with COVID-19?
Current evidence suggests that the severity of COVID-19 disease is higher among smokers. Smoking impairs lung function, making it more difficult for the body to fight off respiratory disease due to the new coronavirus.Tobacco users have a higher risk of being infected with the virus through the mouth while smoking cigarettes or using other tobacco products. If smokers contract the COVID-19 virus, they face a greater risk of getting a severe infection as their lung health is already compromised.
How long does it take for symptoms of the coronavirus disease to appear?
On average it takes 5–6 days from when someone is infected with the virus for symptoms to show, however it can take up to 14 days.
What are the typical side effects of dexamethasone during COVID-19 treatment?
See full answer
Dexamethasone is generally safe. It presents a favourable benefit-risk profile, particularly in patients with severe forms of pneumonia, while the benefit is less prominent in patients with non-severe pneumonia. As the treatment is short, even at high doses, corticosteroids are not associated with serious side effects. Potentially higher blood glucose levels (hyperglycaemia) are temporary.Prolonged use (I.e., used for more than two weeks) may be associated with adverse events such as glaucoma, cataract, fluid retention, hypertension, psychological effects (e.g., mood swings, memory issues, confusion or irritation), weight gain, or increased risk of infections and osteoporosis.To reiterate: All these adverse events are not associated with short term use (with the exception of hyperglycaemia that can worsen diabetes).

In what conditions does COVID-19 survive the longest?
Coronaviruses die very quickly when exposed to the UV light in sunlight. Like other enveloped viruses, SARS-CoV-2 survives longest when the temperature is at room temperature or lower, and when the relative humidity is low (<50%).
