  • Rubella Vaccine 

    The RA 27/3 strain of rubella virus was developed at The Wistar Institute. The seed stock from RA 27/3 has been successfully used worldwide since the 1970's as a vaccine for the prevention of rubella infection. This vaccine has been administered alone and as part of a combination vaccine (e.g. MMR; measles, mumps, rubella vaccine).

    The Wistar Institute has maintained seed stocks of the RA/ 27/3 strain of rubella for use in production of vaccines. These vaccines have been licensed to regional public health agencies and to for-profit companies who are developing vaccines for local distribution, particularly in Asia and South America.

  • Rabies Vaccine - PM Seed Stock 

    The PM 1503 strain of rabies virus, developed at The Wistar Institute, has been successfully used worldwide to develop rabies vaccine for post-exposure treatment to prevent rabies infection of humans.

    The Wistar Institute has seed stock of the PM 1503 strain of rabies for use in production of vaccines. The Wistar seed stocks were grown on Vero cells, however, they can be adapted to grow on human diploid cells. This rabies vaccine seed stock has been licensed to select regional public health agencies and to for-profit companies who are developing vaccines for local distribution in selected countries, particularly China and India.
