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.
Vaccine effectiveness varies from greater than 95% (for diseases such as measles, rubella, hepatitis B) to much lower (influenza this year 23%, and 60% in years with a good match of wild and vaccine viruses, and the acellular pertussis vaccines after 5 years or so provide only about 70% protection).pproximately 5 to 15% of susceptible people who receive MMR vaccine will develop a low-grade fever and/or mild rash 7 to 12 days after vaccination. However, the person is not infectious, and no special precautions (such as exclusion from work) need to be taken.
