Is Taking Flu Vaccine Three Months Prior To IVF Safe?

I am due to start my second attempt of IVF at the end of January. I have been offered the flu vaccine at work but it says not to have it if trying to concieve. Do you think it would be safe to have bearing in mind my treatment is over three months away. I have been put on the pill until then so I am very unlikely to concieve in the meantime.
