J&J Vaccine Availability
J&j vaccine availability. The J&J vaccine uses a different approach to instruct human cells to make the SARS-2 spike protein, which then triggers an immune response. It is what’s known as a viral vectored vaccine. A harmless adenovirus — from a large family of viruses, some of which cause common colds — has been engineered to carry the genetic code for the SARS-2 spike protein. Once the adenovirus enters cells, they use that code to make spike proteins. J&J employed this same approach to make an Ebola vaccine that has been authorized for use by the European Medicines Agency.
Vaccines protect against many different diseases, including:
- Cervical cancer
- Hepatitis B
- Japanese encephalitis
- Yellow fever
Some other vaccines are currently under development or being piloted, including those that protect against Ebola or malaria, but are not yet widely available globally.
Not all of these vaccinations may be needed in your country. Some may only be given prior to travel, in areas of risk, or to people in high-risk occupations. Talk to your healthcare worker to find out what vaccinations are needed for you and your family.
Virtually all cervical cancer cases start with a sexually transmitted HPV infection. If given before exposure to the virus, vaccination offers the best protection against this disease. Following vaccination, reductions of up to 90% in HPV infections in teenage girls and young women have been demonstrated by studies conducted in Australia, Belgium, Germany, New Zealand, Sweden, the United Kingdom and the United States of America.
In studies, the HPV vaccine has been shown to be safe and effective. WHO recommends that all girls aged 9–14 years receive 2 doses of the vaccine, alongside cervical cancer screening later in life.
