The cytoplasm of a bacterial cell contains the deoxyribonucleic acid (DNA) molecules that make up the bacterial genome (or nucleoid), the transcriptional machinery that copies DNA into ribonucleic acid (RNA), and the ribosomes that translate the messenger RNA information into protein sequence.
Influenza vaccine is recommended for all people over 6 months of age, it is an inexpensive way of protecting yourself, your family and your community from the spread of influenza. How long does protection from the vaccine last? The vaccine takes about 2 weeks to work and will last for about 12 months.
The first dose protects your body (for the short-term) in an estimated two to four weeks. Once you receive the second dose (about six to 12 months after the first), the vaccine should work for at least 20 years. Studies estimate, however, that the vaccine may last over the course of your lifetime.
