Answer: False
Explanation: Vaccines are biological products that are difficult to produce and have a lengthy manufacturing process thus, these and among other factors play specific roles as to why there exists shortages. Causes for shortages of vaccines are both complex and interrelated, and can vary for different products and countries. Some known causes include: limited number of manufacturers, market conditions—low market prices, fluctuations in global demand etc are are a number of causes for shortages. The regulation of quality systems is essential in ensuring that all pharmaceutical products, not just vaccines, meet the standards set by regulators, and that they are safe for use by its intended users. Therefore, tighter regulations,
resultant lower costs and risks of development of vaccines have not contributed to the recent shortage of vaccines.
