Swine vaccines
Vaccinations are available for a number of diseases that affect swine. In some cases vaccination constitutes the major part of the control of the disease. In many other cases it is only a small part of the control program. Vaccination programs need to be tailored to each swine operation. Remember that vaccination only raises a pig's level of resistance. If other important management procedures are neglected, even this elevated level of resistance may be inadequate to prevent disease.
Vaccines must be stored and administered according to label directions if they are to be effective. Slaughter withdrawal time must be observed at all times to avoid illegal residues. The most common times for administering many vaccines are before breeding and before farrowing. This protects the sow and passes antibodies to the piglets for their protection.
In recent years, in an effort to reduce their costs, there has been a tendency for producers to chop and change their vaccination programmes.
Such changes have been exacerbated by withdrawal of certain commercial vaccines, for example Suvaxyn E coli.
Not all vaccines used against one disease, such as E coli, are identical or necessarily compatible, points out Mark White, veterinary consultant to JSR Genetics. Where a two-dose primary course is required it may not be appropriate to use...

Vaccination has so far failed to localize the outbreak of an epidemic of pig plague at a farm in Russia’s Vladimir Region bordering on the Moscow Region, the deputy head of the local state veterinary inspector told Itar-Tass on Wednesday.
According to Nikolai Mitrofanov, a total of 200 pigs have already died since Tuesday night, and 300 more have fallen ill.
Specialists have already vaccinated the entire stock of 2,000 pigs, and the farm has been put on quarantine.

UK livestock disease curbs strengthened but not infallible.
Nearly four years since Britain's farms were ravaged by foot-and-mouth disease, the country could still do more to thwart a repeat outbreak, according to the Royal Society.
Four million sheep, cows and other animals were slaughtered in 2001 in a desperate effort to control the most serious British epidemic of foot-and-mouth disease in over 30 years. At the time, authorities were criticised for their lack of preparedness....

The UK could not effectively tackle foot-and-mouth disease using emergency vaccination if another outbreak were to occur in the immediate future.
That is the view of the Royal Society which published a report on Tues (Dec 21) reviewing the work undertaken by DEFRA to ensure the UK is better prepared for a future outbreak.
The report recognises that the government has already done significant work, but it also identifies problems with the use of emergency vaccination that urgently need to...
