Optimization of all experimental conditions including composition of mobile phase, flow rate, and column temperature was carried out step by step, and the method validity of the developed method was examined according to international validation guidelines. Calibration range, linearity, the limit of determination, the limit of quantification, robustness, accuracy from commercial tablet samples, and method stability were examined in detail.

However, pregnant and lactating women are excluded from clinical trials of vaccines due to the unknown effects of the vaccine on the expectant mother, fetus, and infant. Pregnancy and the following lactation periods are long processes with unique physiological, psychological, and pathological characteristics, in which many practices are discussed for the mother and the baby. Based on the limited data available on the mechanisms of action of vaccine types, Covid 19 vaccines cannot possibly cause any risk to pregnant women and nursing mothers. On the other hand, there is currently insufficient data on the safety of Covid 19 vaccines in pregnant and lactating women. \u0000Result and Discussion: Evidence-based and personalized information about vaccines is needed to support pregnant and breastfeeding women's decision-making about vaccines. Vaccination should be recommended to all pregnant and lactating women after they have been sufficiently informed about the advantage and risks of Covid 19 vaccines and their consent has been obtained.
