Most of the time, people with chronic hepatitis C have no symptoms at the time of infection and no symptoms for years or even decades of chronic infection.
Although having any symptoms at all is rare, if they do occur, they usually go away within a few weeks.Īround 15-25% of people who are infected will spontaneously fight off the virus on their own and they will not have a chronic hepatitis C infection and no long term damage occurs.īut around 75-85% of people will develop chronic infection.

Occasionally people experience fatigue, loss of appetite, weakness or sometimes having a yellow color in their skin or eyes. When someone is first infected with hepatitis C, most likely they have no symptoms and are unaware.

What’s more, companies like Moderna are developing updated vaccines to specifically target these variants, with positive early results. For example, Israel began its mass vaccination campaign during their third wave, and quickly saw a decline in new cases. Countries with advanced vaccine rollouts are maintaining good control over the virus. Such variants present two major challenges: they can evade vaccine immunity and, in some cases, are also more transmissible.Īlthough variants have spread widely throughout the world, there are several pieces of good news on this front. These are strains of the SARS-CoV-2 virus that carry changes which make them harder to control by immunisation. Variants of the coronavirus are also concerning. Why do we need booster shots, and could we mix and match different COVID vaccines? Scientists are actively monitoring people who’ve had COVID-19 vaccines to understand how long vaccine immunity is likely to last, and if and when booster shots will be required. But immunity, even from the vaccines, fades over time. Reducing the risk of transmitting the coronavirus relies on developing strong immunity against the virus. But if we're all vaccinated, we'll be safe from the worst We may never achieve long-term global herd immunity for COVID. This also greatly increases the opportunity to achieve some degree of population (or “herd”) immunity, and a faster easing of social restrictions. Breaking chains of transmission within the community and limiting onward spread is critical to help protect people who may respond poorly to immunisation or may not be able to get vaccinated themselves, such as children, some older people, and some people who are immunocompromised. If COVID-19 vaccines reduce the chances of transmitting the virus, then each person who is vaccinated protects not only themselves, but also people around them. 
Indeed, between April 10 and May 1, six people in hotel quarantine in New South Wales tested positive for COVID-19, despite being fully vaccinated.īut how likely are vaccinated people to actually pass the virus on, if they do get infected? Evidence is increasing that, not only do COVID-19 vaccines either stop you getting sick or substantially reduce the severity of your symptoms, they’re also likely to substantially reduce the chance of transmitting the virus to others. We call these cases “breakthrough” infections. However, even the best vaccines we have are not perfect, which means some vaccinated people still end up catching the virus. Efficacy against symptoms of the disease in clinical trials has ranged from 50% ( Sinovac) to 95% ( Pfizer/BioNTech), and similar effectiveness has been reported in the real world. Their primary purpose is to prevent you from getting really sick with the virus, and it quickly became clear the vaccines are highly efficient at doing this. Since COVID-19 vaccines began rolling out across the world, many scientists have been hesitant to say they can reduce transmission of the virus.
