And to those who doubt the use of aborted fetal tissue for the vaccines mentioned, here's the package insert for the chickenpox vaccine.
Hey, there's some baby cow serum in there as well... and guinea pig stuff in there too, how apropos.
VARIVAX® [Varicella Virus Vaccine Live (Oka/Merck)] Contents Description Clinical Pharmacology Indications and Usage Contraindications Warnings Precautions Adverse Reactions Dosage and Administration How Supplied References DESCRIPTION VARIVAX* [Varicella Virus Vaccine Live (Oka/Merck)] is a preparation of the Oka/Merck strain of live, attenuated varicella virus. The virus was initially obtained from a child with natural varicella, then introduced into human embryonic lung cell cultures, adapted to and propagated in embryonic guinea pig cell cultures and finally propagated in human diploid cell cultures (WI-38). Further passage of the virus for varicella vaccine was performed at Merck Research Laboratories (MRL) in human diploid cell cultures (MRC-5) that were free of adventitious agents. This live, attenuated varicella vaccine is a lyophilized preparation containing sucrose, phosphate, glutamate, and processed gelatin as stabilizers. VARIVAX, when reconstituted as directed, is a sterile preparation for subcutaneous administration. Each 0.5 mL dose contains the following: a minimum of 1350 PFU (plaque forming units) of Oka/Merck varicella virus when reconstituted and stored at room temperature for 30 minutes, approximately 25 mg of sucrose, 12.5 mg hydrolyzed gelatin, 3.2 mg sodium chloride, 0.5 mg monosodium L-glutamate, 0.45 mg of sodium phosphate dibasic, 0.08 mg of potassium phosphate monobasic, 0.08 mg of potassium chloride; residual components of MRC-5 cells including DNA and protein; and trace quantities of sodium phosphate monobasic, EDTA, neomycin, and fetal bovine serum. The product contains no preservative. To maintain potency, the lyophilized vaccine must be kept frozen at an average temperature of - 15°C(+5°F) or colder and must be used before the expiration date (see HOW SUPPLIED, Stability and Storage). Storage in any freezer (e.g., chest, frost-free) that reliably maintains an average temperature of -15°C (+5°F) or colder and has a separate sealed freezer door is acceptable.
