The Gamaleya COVID-19 vaccine, also known as EpiVacCorona, is a subunit vaccine that was authorized for emergency use in some countries worldwide to help curb the ongoing COVID-19 pandemic.
A subunit vaccine is made up of a specific part of the microbe, rather than the whole microbe. In the case of the Gamaleya vaccine, it is made up of a part of the spike protein found on the surface of the SARS-CoV-2 virus, which causes COVID-19. When the vaccine is injected into the body, it triggers an immune response, including the production of antibodies, that will help protect against future COVID-19 infection.
The Gamaleya COVID-19 vaccine was developed by the Gamaleya Research Institute of Epidemiology and Microbiology in Russia and it was authorized for emergency use by the Russian Ministry of Health in December 2020, following clinical trials involving less than 5,000 participants. In the trials, the vaccine was found to be around 92% effective in preventing COVID-19, including severe disease.
The Gamaleya vaccine is given as a series of two doses, with the second dose administered 21 days after the first. The vaccine has been shown to be effective in people of all ages, including those over 55, who are at an increased risk of severe illness or death from COVID-19.
Like all vaccines, the Gamaleya COVID-19 vaccine can cause side effects, although these are generally mild and short-lived. Common side effects include pain and redness at the injection site, fatigue, headache, muscle and joint pain, chills, fever, and nausea. These side effects generally go away on their own within a few days.
The Gamaleya COVID-19 vaccine has been authorized for emergency use in some countries, including Russia, Belarus, and Kazakhstan. It has been given to thousands of people worldwide and has been shown to be safe and effective in preventing COVID-19.
The Gamaleya COVID-19 vaccine is an important tool in the fight against the ongoing pandemic, and it is part of a comprehensive strategy that includes testing, contact tracing, and other public health measures to slow the spread of the virus.
It’s important to mention that the Gamaleya COVID-19 vaccine is not a cure for COVID-19, but it can help to prevent severe illness, hospitalization, and death from the disease. Vaccination is a crucial step in controlling the pandemic and helping to return to a sense of normalcy. It’s also important to note that the vaccine was authorized for emergency use in Russia before the completion of phase 3 clinical trials, and the data from the clinical trials has not been released for independent review.
