Last updated…, What is the Omicron variant? , The Omicron variant of COVID-19 has been called a variant of concern by WHO based on the evidence that it has several mutations that may have an impact on how it behaves. There is consistent evidence that Omicron is spreading significantly faster than the Delta variant in countries with documented community transmission, with a doubling time of 2-…, How did the Omicron variant develop? , When a virus is circulating widely and causing numerous infections, the likelihood of the virus mutating increases. The more opportunities a virus has to spread, the more opportunities it has to undergo changes. New variants like Omicron are a reminder that the COVID-19 pandemic is far from over. It is therefore essential that people get the…, Where is the Omicron variant present? , Omicron has now been detected in most countries, after the variant was first detected in November 2021.   , Is the Omicron variant more severe than other COVID-19 variants? , Early findings suggest that there is a reduced risk of hospitalization for Omicron compared to the Delta variant. But WHO warns that it should not be dismissed as “mild”. Increased transmission is expected to lead to more hospitalizations. That increase causes strain on frontline workers and healthcare systems, which in turn can result in more…, Is the Omicron variant more contagious? , Yes, the Omicron variant is more contagious than previous variants. However, being vaccinated and taking precautions such as avoiding crowded spaces, keeping your distance from others and wearing a mask are critical in helping to prevent the spread of COVID-19, and we know these actions have been effective against other variants.   > See other…, Does the Omicron variant cause different symptoms?  , There is no information to suggest that Omicron causes different COVID-19 symptoms from other COVID-19 variants.  , Are the COVID-19 vaccines effective against the Omicron variant?  , Researchers are looking into any potential impact the Omicron variant has on the effectiveness of COVID-19 vaccines.

However, WHO reports that so far it looks…, Is a prior COVID-19 infection effective against the Omicron variant?, WHO reports that early evidence suggests that previous infection could offer less protection against Omicron in comparison to other variants of concern, such as Delta. Information is still limited though and we will share updates as it becomes available. You should get vaccinated even if you’ve previously had COVID-19. While people who recover…, Do current COVID-19 tests detect the Omicron variant? , The widely used PCR and antigen-based rapid diagnostic tests continue to detect infection of COVID-19, including Omicron.  , Are children more likely to contract the Omicron variant? , Research is ongoing into Omicron’s transmissibility and we will update as more information becomes available. However, people who are mixing socially and those who are unvaccinated are more susceptible to contracting COVID-19.  , How can I protect myself and my family against the Omicron variant?, The most important thing you can do is reduce your risk of exposure to the virus. To protect yourself and your loved ones, make sure to:  Wear a mask that covers your nose and mouth. Make sure that your hands are clean when you put on and remove your mask. Keep a physical distance of at least 1 metre from others.  Avoid poorly ventilated or…, How can I talk to my child about the Omicron and other COVID-19 variants?, News about COVID-19 and now the Omicron variant is flooding our daily lives and it is only natural that curious young children will have questions – lots of them.

What you need to know about COVID-19 vaccines

Vaccines save millions of lives each year. The development of safe and effective COVID-19 vaccines is a huge step forward in our global effort to end the pandemic and to get back to doing more of the things we enjoy with the people we love. We’ve gathered the latest expert information to answer some of the most common questions about COVID-19…, How do COVID-19 vaccines work?, Vaccines work by mimicking an infectious agent – viruses, bacteria or other microorganisms that can cause a disease. This ‘teaches’ our immune system to rapidly and effectively respond against it.  Traditionally, vaccines have done this by introducing a weakened form of an infectious agent that allows our immune system to build a memory of it.…, Are COVID-19 vaccines safe?, Yes, even though COVID-19 vaccines are being developed as rapidly as possible, they must go through rigorous testing in clinical trials to prove that they meet internationally agreed benchmarks for safety and effectiveness. Only if they meet these standards can a vaccine receive validation from WHO and national regulatory agencies. UNICEF will…, How were COVID-19 vaccines developed so quickly?, Thanks to the unprecedented investment in research and development and global cooperation, scientists were able to develop safe and effective vaccines against COVID-19 in record time. All the standard safety procedures and rigorous regulatory standards were maintained. In addition to the COVID-19 vaccines currently in use in many countries around…, Which COVID-19 vaccine is best for me?, All WHO-approved vaccines have been shown to be highly effective at protecting you against severe illness from COVID-19. The best vaccine to get is the one most readily available to you!, Will the COVID-19 vaccines work against the new variants?, WHO says that the vaccines approved to date are expected to provide at least some protection against new variants. Experts around the world are continuously studying how the new variants affect the behaviour of the virus, including any potential impact on the effectiveness of COVID-19 vaccines. Should any of the vaccines be shown to be less…, Who should be vaccinated first?, As there is not enough manufacturing capacity in 2021 to meet all global needs, not everyone will be able to get the vaccine at the same time. Countries must identify priority populations, which WHO recommends are frontline health workers (to protect health systems) and those at highest risk of death due to COVID-19, such as older adults and…, When shouldn’t you get a COVID-19 vaccine?, If you have any questions about whether you should receive a COVID-19 vaccine, speak to your doctor. At present, people with the following health conditions should not receive a COVID-19 vaccine to avoid any possible adverse effects: If you have a history of severe allergic reactions to any ingredients of a COVID-19 vaccine. If you are currently…, Should I get a vaccine if I’ve already had COVID-19?, Yes, you should get vaccinated even if you’ve previously had COVID-19. While people who recover from COVID-19 may develop some natural immunity to the virus, we do not yet know how long it lasts or how well you are protected. Vaccines offer more reliable protection., Should I get the COVID-19 vaccine if I’m breastfeeding?, Researchers are currently studying COVID-19 vaccination in breastfeeding women, but there is still limited information at this time. WHO advises that vaccinations are offered if a lactating woman is part of a priority group for vaccinations, for example if you are a health worker. Breastfeeding can continue after vaccination and remains one of the…, Should I get the COVID-19 vaccine if I’m pregnant?, Although the overall risk of severe illness from COVID-19 remains low, pregnancy puts you at higher risk of severe illness compared to people who are not pregnant. Research is still ongoing to understand the safety and effects of COVID-19 vaccination in pregnant women, but there is no known reason that would outweigh the benefits of vaccination…, Can COVID-19 vaccines affect fertility?, No, you may have seen false claims on social media, but there is no evidence that any vaccine, including COVID-19 vaccines, can affect fertility in women or men. If you are currently trying to become pregnant, you do not need to avoid pregnancy after receiving a COVID-19 vaccine., Should my child get a COVID-19 vaccine?, Children’s immune systems are different from those of adults and can vary significantly depending on their age. At present, WHO-approved COVID-19 vaccines are not recommended for anyone under the age of 16-18 years (depending on the individual vaccine), even if they belong to a high-risk group. Children were not included in the initial trials for…, When will a COVID-19 vaccine be available in my country?, The distribution of vaccines is underway globally and the vaccine availability varies by country. We recommend checking with your health ministry to get the latest information for your country. On behalf of the COVAX Facility, UNICEF is procuring COVID-19 vaccines and delivering them around the world to make sure no country is left behind. Our…, What is COVAX?, COVAX is part of a global effort aimed at accelerating the development and manufacture of COVID-19 vaccines, and to guarantee fair and equitable access around the world.

Get verified facts and advice from trusted sources like your local health authority, the …, Can COVID-19 vaccines affect your DNA?, No, none of the COVID-19 vaccines affect or interact with your DNA in any way. Messenger RNA, or mRNA, vaccines teach the cells how to make a protein that triggers an immune response inside the body. This response produces antibodies which keep you protected against the virus. mRNA is different from DNA and only stays inside the cell for about 72…, Do the COVID-19 vaccines contain any animal products in them?, No, none of the WHO-approved COVID-19 vaccines contain animal products., How can I protect my family until we all receive a COVID-19 vaccine?, Safe and effective vaccines are a gamechanger, but it is still not clear the degree to which they can protect us against infection and transmission. For the time being, even once vaccinated we need to continue taking precautions to protect ourselves and others. This includes wearing masks, physical distancing and regular handwashing. This article…
