While Hepatitis A is not part of the routine pediatric series, it is required frequently for people who work in the food handling and other industries.HAVRIX is also offered in combination with the Hepatitis B vaccine, trade name TWINRIX (Glaxo Smith Kline). The Hepatitis B vaccine component does not rely on viral culture; it uses recombinant DNA technology.The purpose of childhood rubella vaccination is not to protect the child, as German measles is a mild illness in children, and, as with chickenpox in children, natural infection confers lifelong immunity.

Vaccine safety is a profoundly important issue since, in a population - wide program, even rare events turn into large numbers: a tiny fraction of a huge number is a big number.
Every effort should be made to monitor, ensure, and improve vaccine safety, and if questions regarding a vaccine or a component of a vaccine come up, they should be rigorously investigated. In general, the vaccine is far, far safer than the disease it is attempting to prevent. To repeat: the first point of this paper is to review the issue of the moral status of parents who use vaccines manufactured with cell cultures derived from aborted babies.
But I think this is an important topic, even more important than the embryonic stem cell problem because, unlike stem cells (whose applications are, at this point, science fiction) this is upon us now Also, this is a long essay, well over 7000 words, and the internet just isn't a great medium for long writings (I don't like reading things more than 1000 words or so on a computer screen; gives me a headache).
So, like the stem cell series (which has not been published elsewhere, but is forming the basis of the stem cell chapter in the book) I will break it up into bite sized chunks over the next several weeks.
We'll see how it goes, so here goes: Human Technology Manufacturing Platforms, Part I (of VII or so parts).
The topic of vaccines manufactured using cell lines which have their origin in aborted babies has received a fair amount of attention in the Catholic press, and the topic again became prominent with the publication of a Vatican letter on the topic in July, 2005.
I believe that the issue is poised to move out of this relatively circumscribed arena to affect virtually everyone, and quite soon.
This is because numerous new vaccines using illicit human cell lines as culture media, including new vaccines against influenza A and B, and the avian flu vaccine, are well into the development phase, and in some cases already entering clinical trials.
The first vaccine, rubella, is usually given as a component of the combined measles/mumps/rubella vaccine M-M-R II (Merck.), and the rubella vaccine component uses a live, attenuated rubella virus strain designated RA 27/3, grown in the human diploid cell line WI-38. The rubella vaccine is also available as a single injection from the same manufacturer under the trade name MERUVAX, and also uses the WI-38 cell line. The measles and mumps vaccine components in the combination M-M-R II vaccines are grown in chick embryo cultures, and therefore don't present a moral problem.
The second major vaccine is a vaccine against varicella, VARIVAX (Merck).
