[QUOTE="wbvs58, post: 1514390, member: 16453"] Ron, most vaccines and toxoids will give protective levels of antibodies after the first injection after about 10 days however this protective level is only short lived and by 6-8 weeks may drop below protective levels and this is why the 2nd dose is required, it will give an immune response much quicker 24-48 hrs and then give the longer level of protection. The 1st dose primes the system and 2nd dose immediately recognises the challenge from prior exposure and jumps on it. Ken [/QUOTE]
