The vaccines are all combined together so you can't just have one, we target the wrong age groups
No we don't, we target the age group that will stop the disease spreading. We have virtually eliminated rubella from the uk, which wasn't happening before when it was limited to teenage girls getting the vaccine.
In the past 1 in 5 adults did not get rubella as a child, hence the numbers of CRS and adults getting more serious complications. In the 60s in US epidemic there were also 10's of 1000s of miscarriages and still births due to Rubella
the green book says
"Clinical diagnosis is unreliable as the
rash may be fleeting and is not specific to rubella" which is why you need a blood test.
However I was diagnosed in the middle of a true epidemic in the 70s and was diagnosed because of the lumps behind my ears as per the NHS and not part of Cote's diagnosis. This was a few weeks before I was due to have the vaccine myself and was caught from my mother who was in her late 30s by then.
"If you have rubella, the glands behind the ears, below your skull at the back of your head, and in your neck usually swell. In some cases, this swelling can be painful"
and agree Bertrandrussell the moral objection is weird. Especially as the risk from the disease (see my link above) is more than the risk of vaccine.
