rabies inactivated virus (whole) usually lyophilized usually none 2° - 8 °c very stable in lyophilized form and not freeze sensitive rubella live attenuated virus lyophilized none -50° - 8 °c can be stored at -20 °c and more stable than measles vaccines tetanus toxoid purified protein liquid aluminum based 2° - 8 °c very heat stable and resistant to temperature up to 55 °c, but freeze sensitive. tuberculosis live attenuated baacterium lyophilized none 2° - 8 °c not freeze and light sensitive varicella live attenuated virus lyophilized none -50 °c - -15 °c not freeze sensitive. but relatively unstable at elevated. temperature due to the abundant number of vaccines, pharmaceutics combines two or more vaccines to save more time. these types of vaccines might change in storage temperature recommendation due to the additional stability of each vaccine. table 3. combination vaccines storage temperature recommendation vaccine general name vaccine type formulation adjuvant recommended temperature description diphtheria, tetanus, pertussis dtap purified protein liquid aluminum based 2° - 8 °c freeze sensitive dtwp purified protein, inactivated bacteria liquid aluminum based 2° - 8 °c freeze sensitive but relatively heat stable hepatitis a and b recombinant protein, inactivated virus liquid aluminum based 2° - 8 °c freeze sensitive but relatively heat stable measles, mumps, and rubella mmr live attenuated virus lyophilized none -50° - 8 °c not freeze sensitive and relatively stable in the lyophilized state.
