In this era, technology has advanced small devices such as laptop, tablet and mobiles. Their productivity has also been increased. We know that each device has different screen sizes. Now it has become a challenge for a developer that how to organize a web content and display on screen. In this paper, a comparison of different types of responsive approaches has been presented. These approaches work for various devices of screens. Our main discussion, in paper on Responsive Web Design (RWD), is highly recommended. A discussion has been made in this paper on RWD technologies and tools, issue and review of RWD. The objective of this paper is to find the best approach and suggestion for future work. This paper is guidance for the designers and the developer who will gain a better experience and improve their productivity in this field.

Objective: Recent studies and surveys are detecting an ambiguous trend of routine immunization coverage and fully immunized children in KPK. Pakistan. A cross-sectional survey was conducted to access immunization status among children of age group 12-23 months visiting fixed EPI centers in primary, secondary and tertiary health facilities in rural and urban areas. Methods: The study covered 436 children in five health facilities. Five fixed EPI centers are visited as per office order: BBS teaching hospital Abbottabad. (DHQ), Women and children hospital Abbottabad. (THQ), Type D hospital Havelain, Basic Heath Unit (BHU) Mangal and Ayub teaching hospital Abbottabad (AMI). A pretested structured questionnaire was used to collect information. Analysis was performed on SPSS version 23 for frequencies, cross tabulation and percentages. Results: Estimation recorded fully immunized children as 275 (63.1%), partially immunized as 155 (35.6%), and unimmunized as 6 (1.3%). Only 157 (36.1%) children in rural area were fully immunized compared to 118 (27.1%) in urban. Primary respondents were mothers 320 (73.4%) whereas, father and other respondents are almost 13%. Vaccination cards were available with 386 (88.5%) respondents. High proportion of partially immunized children 77% in BHU. However, unimmunized 1.96% and 4.4% children in AMI and Type D hospital were present. Moreover 67% partially immunized are from rural origin. The coverage of various vaccines was BCG 421 (96.6%), Pentavalent 403 (96.6%): Penta-1 60 (13.8%), Penta-2 38 (8.7%), Penta-3 305 (70.0%), and Measles 375 (86.0%): Measles-1 127 (29.1%), Measles-2 248 (56.9%), and Polio 430 (98.6%): Oral Polio Vaccine (OPV-0) 51 (11.7%), OPV-1 32 (7.3%), OPV-2 44 (10.1%), OPV-3 165 (37.8%), Injectable polio vaccine (IPV) 138 (31.7%), Pneumococcal 409 (93.8%): Pneumo-1 75 (17.2%), Pneumo-2 46 (10.1%), Pneumo-3 288 (66.1%). No Sex-wise discrimination was found. Conclusion: Hard work in policy making is needed to strengthen routine immunization programme in marginalized areas like rural areas (83.12% of KPK and 62.5% of Pakistan) with special emphasis on BHUs and groups such as those living in mountainous terrain. Inaccessibility, inconvenience and unavailability of timely EPI services at BHUs are among various reasons of unimmunized and partially immunized children. Targeted intervention are needed with special emphasis on people in slum and rural areas with low educational and socioeconomic status.
